The original line's equation is y = -2x + 3


To find inverse of a function, you switch y and x and then solve for y =.


x = -2y + 3

x-3 = -2y

(x-3)/-2 = y


y=(x-3)/(-2)


You can then guess and check.


If x is 0:


(0-3)/-2 = 3/2 ≠3


If x is 3:


(3-3)/-2 = 0 = 0


Check the others just to make sure.


If x is 1:


(1-3)/-2 = 1 ≠ -1


If x is -1:


(-1-3)/-2 = 2 ≠ 5
