Step-by-step explanation:
We can calculate a few points, such as when x = 0, y = 0 (which sometimes doesn't happen), and the lowest point (where y is the smallest)
When x = 0, y = 3, so (0,3) is one of the points, and is also the y intercept
When y = 0, x = -3, and it also happens that 0 is the lowest point that y can be, since no value of x would make y negative.
Now, we have two points, (0,3) and (-3,0)
Graph B is the one one which has both the points (0,3) and (-3,0) on it, and indeed, y never reaches below the x axis since y can't be negative

The following lines is perpendicular, y=-x+6 and y=x+1
Step-by-step explanation:
Slope of parallel lines are equal(ex. slope of 2 stays 2 )
Slope of perpendicular lines to another is the negative reciprocal(ex. slope of 2 becomes -1/2)
y = -x + 6 and y = x + 1
the slope for y = -x + 6 is -1 (-1/1)

How to apply rigid transformations on a point
Herein we must apply a rigid transformation into a given point to determine an image. Rigid transformations are transformations applied on a geometric locus such that Euclidean distance is conserved. Dilations are a kind of rigid transformations such that:
(x, y) → (k · x, k · y), for k > 0
If we know that Q(x, y) = (0, 2) and k = 0.5, then the coordinates of Q' are:
Q'(x, y) = (0.5 · 0, 0.5 · 2)
Q'(x, y) = (0, 1)

What is a transformation?Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.
Dilation is the increase or decrease in the size of a figure.
A rigid transformation such as reflection, rotation and translation preserve the shape and size, hence the pre-image and image have the same corresponding angle and side measures.
A non rigid transformation such as dilation preserve the shape and not size, hence the pre-image and image have the same corresponding angle measures.

Answers
The equation has no solutions when m = 0, and when m ≠ 0, the equation has only one solution.
For what values of m we have a single solution?
Here we have the equation:
m*x = 5
If we solve for x, we get:
x = 5/m
So, as long as m is different than zero, we will have one solution.
We can't have m = 0 because we can't divide by zero.
Then:
m > 0 or m < 0.
When we have no solutions?We have no solutions when m = 0, the equation becomes:
0*x = 5
0 = 5

Answers
Answer:
m = 2/3
Step-by-step explanation:
Rewrite in slope-intercept form.
y = -3/2x + 7/2
Using the slope-intercept form, the slope is −3/2.
m = -3/2
The equation of a perpendicular line to y=−3/2x + 7/2 must have a slope that is the negative reciprocal of the original slope.
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
• First rewrite the original equation in the form y = mx + c ,
where m = gradient:
[tex]3x + 2y = 7[/tex]
⇒ [tex]2y = -3x + 7[/tex]
⇒ [tex]y = \frac{-3}{2}x + \frac{7}{2}[/tex]
• From this equation, we can see that the gradient, m = [tex]\frac{-3}{2}[/tex] .
The gradient of a line perpendicular to another line with gradient m, = [tex]\frac{-1}{m}[/tex].
∴ gradient of perpendicular = -1 ÷ [tex]\frac{-3}{2}[/tex]
= [tex]\frac{2}{3}[/tex]
