Answer:

y = -3x -16

Step-by-step explanation:

For problems like this, I like to start with a variation of the point-slope form of the equation of a line:

y = m(x -h) +k . . . . . for a line with slope m through point (h, k)

For your given values, this is ...

y = -3(x +3) -7

y = -3x -9 -7 . . . . eliminate parentheses; next, combine terms

y = -3x -16

Hope this helps! ;)

Now, we can write this as the image

To write this as the image, we simply have to add a mark on the A

This mark is at the upper right

We have it as A’ (x,y)

The part added is called a prime
