Dilation refers to a non rigid motion where a figure is transform and its image has the same form but a different size measure.
Dilation is define by the rule (x,y)-- (kx, ky) where k represents the scale factor.
On this exercise is given that a triangle with vertices (-2,1), (8,4), and (3,0) was dilated by a scale factor of four, and it is asked to find the vertices of the image of the triangle after the dilation occurred.
Pre-image Image
(-2,1) -- (-2*4,1*4) -- (-8,4)
(8,4) -- (8*4,4*4) -- (32,16)
(3,0) -- (3*4,0*4) -- (12,0)
The coordinates representing the vertices of the triangle's image are (-8,4), (32,16), and (12,0); meaning that the ordered pair which is not a coordinate for a point in the triangle's image is (2,1).
The answer is 
First you must use distributive property to simplify.
Then, you must subtract 18 on both sides
Next, add 2 on both sides
Then, subtract 8x on both sides
Finally, Divide both sides by -2. Don't forget to switch the equality sign because the variable was changed to a positive using division.

Answer:
Let's solve your equation step-by-step.
x−7=−2
Step 1: Add 7 to both sides.
x−7+7=−2+7
x=5
Step-by-step explanation:
Step 1: Add 7 to both sides.
x−7+7=−2+7
x=5
