14.) write an equation of a line with the given slope and y-intercept.
m = 1, b = 4

a.) y = x – 4

b.) y = x + 4

c.) y = 4x + 1

d.) y = –1x + 4

y= x +4

Step-by-step explanation:

m = slope and b= y-intercept.

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.
