Hi,
question states its inverse function is perpendicular to 2x +2y - 3 = 0
4x +2y - 3 = 0
y = -2x + 3/2 slope m = -2
standard slope intercept form of an equation of a line is
y= mx + b
two lines with slopes that are negative reciprocals of each other are perpendicular to each other
inverse function would have a slope m = (1/2)
y = (1/2)x + b
The procedure for finding the inverse of a linear function is fairly basic.
1. Switch “x” and “y”.
2. Solve for “y”.
x = (1/2)y + b
2x - 2b = y
with b = 2 as an ex: (1/2)x + 2 would be the inverse of 2x -4 (blue line)
