Help me please:((

y= -4x+5

Step-by-step explanation:

We can see that for everytime the x value increases the y value decreases by 4

This means that in our equation y=mx+b

m (our slope) = -4

Now it's just a matter of solving for b

you can do this by pluggin in a coordinate

(1,1) for example

1= -4*1+b

1= -4+b

b=5

Therefore the equation is y= -4x+5

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

step-by-step explanation:

mean or average is 40.6
