Write an equation of a line that passes through the point (7, 3) and is parallel to the line y = negative 2 over 3 x + 3.

The equation of line is y = [tex]\frac{-1}{3}[/tex][tex]x[/tex]+6 .

The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. Key Point. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.

Given that,

equation of given line with a slope of m = 3

y=3x-5​

A line perpendicular to that line will have a slope that is the negative reciprocal of 3.

The reciprocal of 3 is 1/3. So the negative reciprocal of 3 is -1/3.

Therefore, we want to write the equation of a line with slope, m = -1/3, and passes through the point (6, 4) = (x, y).

y = mx + b

4 = (-1/3)(6) + b      

(we've set up the equation with only one unknown, b, that we can now solve for)

4 = -2 + b

b = 6

With a slope, m = -1/3, and a y-intercept, b = 6, the equation of our line relating x and y is:

y = (-1/3)x + 6

Hence, The equation of line is y = [tex]\frac{-1}{3}[/tex][tex]x[/tex]+6 .

Then we can write:

y =12x

3) So, as we can write it y=kx, then the constant of proportionality k =12 because the weight in pounds is 12 times the number of blocks.

the equation for the circle with radius, r = 4 units and center =(4,-7)

will be (x-4)² + (y+7)² = (4)².

When the center and radius of a circle are known, how do you determine its equation?

Use the formula (x-a) ² + (y-b) ² = r ² to determine a circle's equation when you are aware of its radius and center. Here, stands for the circle's center, and is its radius. This equation is essentially a variant way of writing the general equation for a circle.

In this question,

we are given the center of our circle to be,

(4,-7) ≈ (a,b)

thus we are given,

a = 4

and b = -7

and we are given the radius to be 4units

substituting these values in the above equation,

(x-4)² + (y-(-7))² = (4)²

= (x-4)² + (y+7)² = (4)²

Hence the equation for the circle with radius, r = 4 units and center =(4,-7)

will be (x-4)² + (y+7)² = (4)².

The slope of the line passing through the y intercept and the vertex of the quadratic  x²+10x-5 is 5.

The provided quadratic equation is,

y = x²+10x-5

The vertex of a quadratic equation,

(-b/2a, -D/4a)

Where,

a = 1,

b = 10,

c = -5,

D = (b²-4ac)

D = (10²-4(-5)(1))

D = 100+20

D = 120,

Putting all the values to find the vertex of the equation,

(-10/2,-120/4)

(-5,-30)

So, the vertex are now known,

To find the y intercept, putting x = 0 and solving the equation for y,

y = (0)²+10(0)-5

y = -5

The y intercept is,

(0,-5)

If there are two points on the line, let say (a,b) and (c,d), then the slope of the line is,

M = (d-b)/(c-a)

Now, we know two points,(-5,-30) and (0,-5).

We can now find the slope of line,

M = (-5+30)/(0+5)

M = 25/5

M = 5

When the linear correlation coefficient is 1 there is a perfect positive linear relation between the two variables. Scatter diagram would contain points that all lie on a line with a positive slop.

A correlation coefficient is a statistical indicator of how well changes in one variable's value predict changes in another. When two variables are positively linked, the value either rises or falls together.

A correlation coefficient is a metric that expresses a correlation, or a statistical link between two variables, in numerical terms. Two columns of a specific data set of observations, sometimes referred to as a sample, or two parts of a multivariate random variable with a known distribution may serve as the variables.

The strength and direction of the linear links between two sets of variables are evaluated using correlation coefficients. Use Pearson's correlation coefficient if both variables are regularly distributed; otherwise, use Spearman's correlation coefficient.

The final answer is 73.87 degrees.

We have two parallel lines intersected by other line.

We have to relate the angles.

We will take the angle with measure 17° as reference (red angle).

The angle <1 has a measure that is supplementary to the red angle, as <1 is supplementary to the <4, which is a corresponding angle to the red angle.

It has no direct relationship with the red angle.

The angle <2 is supplementary to <1, so it will have the same measure as the red angle (m<2 = 17°).

The relationship with the red angle is that they are alternate exterior angles.

Angle <3 has no direct relationship with the red angle. As it is vertical with <1 it has the same measure (m<3 = 163°) and is supplementary to the red angle.

Angle <4 and the red angle are corresponding angles.

They have the same measure, so they are congruent.

Angle <5 and the red angle form a linear pair, so they are supplementary. The measure of <5 is then m<5 = 163°.

Angle <6 and the red angle are vertical angles, so they have the same measure.

Angle <7 and the red angle form a linear pair, so they are supplementary. The measure of <7 is then m<7 = 163°.

Answer:

Angle <1:

Measure = 163°

Relationship: No name for relationship and supplementary.

Angle <2:

Measure = 17°

Relationship: Alternate exterior and congruent.

Angle <3:

Measure = 163°

Relationship: No name for relationship and supplementary.

Angle <4:

Measure = 17°

Relationship: Corresponding and congruent.

Angle <5:

Measure = 163°

Relationship: Linear pair and supplementary.

Angle <6:

Measure = 17°

Relationship: Vertical and congruent.

Angle <7:

Measure = 163°

Relationship: Linear pair and supplementary.
