I would like to ask anyone if they would mind helping me if they could explain in a way that makes sense, how to find the y-intercept with two points... please help me, google tells me how but my head hurts and it makes no sense TwT ty in advance!!

Answers

Answer:

Ok so the two points that are given need to be in the form of y2-y1 over x2-x1, meaning the x value from the second set of points needs to be subtracted from the x value from the first set of points, and it is the same for the y values. Then that gives you the slope. You add the slope to the equation y=mx+b. The slope is m, so you put the slope in the m spot. If the slope were 3, it would look like y=3x+b because it is in the m spot. Then, you can choose any 1 set of points given and plug it into the equation. I am going to use the slope 3 , like the last example, and plug it in with the set of points. Say the point was (5,2), you will plug the x value, which is 10 in the situation, next to the the slope. The slope will then be 3(5). Then you will plug in the y value, which is 2, into the y place. At the end, the equation will look like this: 2=3(5)+b. Then you multiply 3 and 5, which is 15, and subtract 2 and 15 which will give you -13. The answer will then be -13=b. That is the y-intercept.

Step-by-step explanation:

hey! if you have the equation, for example:

y=3x+4

the y-intercept would be 4! this is an easy hack to use if you already have the equation. in an equation, the number on the very end will always be your y-intercept if it is correctly written in slope intercept form.

if you do not have the equation but have the points, the y-intercept would be the point on the line that touches the y-axis first.

for example:

the line crosses through the 3rd line on the y axis. your y-intercept would be 3. it is the point in which your line crosses on the y-axis line that goes up and down the middle of the graph.

Ms. Garland bought x number of shirts for the new members of her chorus. The cost for X number of shirts, including $3.99 shipping was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. Which equation could be used to find X?
A. 3.99(x + 12.25) = 77.49

B. 3.99x + 12.25 = 77.49

C. 12.25 (x + 3.99) = 77.49


D. 12.25x + 3.99 = 77.49

Answers

77.49 - 3.99 = 12.25 * x

73.5 = 12.25x
(Divide both sides by 12.25)
6 = x
So, she bought six shirts.

the answer is
12/2 = 6
I got 24

Explanation:

12 divided by 1/2 =
12= whole number
1= Numerator
2= Denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
12x2/1 = 24/1
Thus, the answer to 12 divided by 1/2 in fraction form is 24/1
But to make the answer 12 divided by 1/2 in decimal form, you simply divide the numerator from the fraction answer:
24/1 = 24

What is the rate of change of y with respect to x for 25x-4y=50?
(Not multiple choice)

Answers

Answer:

Rate of change is 6.25.

Step-by-step explanation:

The rate of change of y with respect to x is [tex]-\dfrac{25}{4}[/tex].

Important information:

The given equation is [tex]25x-4y=50[/tex].

We need to find the rate of change of y with respect to x.

Rate of change:

The given equation can be written as:

[tex]-4y=-25x+50[/tex]

[tex]y=\dfrac{-25x+50}{4}[/tex]

[tex]y=-\dfrac{25}{4}x+\dfrac{50}{4}[/tex]

Differentiate y with repsect to x.

[tex]y'=-\dfrac{25}{4}(1)+0[/tex]

[tex]y'=-\dfrac{25}{4}[/tex]

Therefore, the rate of change of y with respect to x is [tex]-\dfrac{25}{4}[/tex].

Step-by-step explanation:

My answer: Both are correct because to find the equation u need both the pointslope form and slope intercept form.

Short Answer: Both Samuel and Helena are correct.  Both forms result in the same equation.  Slope-intercept uses slope and a point to find the y-intercept.  Point-slope uses slope and a point to solve for y to form the equation.

Sample Response: Both are correct. Using either form will result in the same equation. The slope-intercept form uses slope and a point to find the y-intercept. Point-slope form uses the slope and a point to solve for y to generate the equation.
