Parallel lines have the same slope, in this case 3.
To find the y intercept we plug in the points (2,1) into y=mx+b, with 2 being x and 1 being y.
1=3(2) + b
Solve this and you get -5 as the y intercept.
The equation is y=3x-5

This is the answer.
Answer:
The image of p is (2.5x , 2.5y)
Step-by-step explanation:
* Lets talk about dilation
- A dilation is a transformation that changes the size of a figure.
- It can become larger or smaller, but the shape of the
figure does not change.
- The scale factor, measures how much larger or smaller
the image will be
- If the scale factor greater than 1, then the image will be larger
- If the scale factor between 0 and 1, then the image will be smaller
* In our problem
- Point p is (x , y)
- Center of dilation is (0 , 0)
- The scale factor is 2.5
* To get the image multiply each coordinates of p by 2.5
∴ The image of p is (2.5x , 2.5y)
