Answer:
y = -2x +8
Step-by-step explanation:
The 2-point form of the equation of a line is useful when two points are given.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (2 -4)/(3 -2)(x -2) +4
y = -2(x -2) +4
y = -2x +8
Step 1. Substitute y for f(x)
Step 2. Switch x and y.
Step 3. Solve for y.
Step 4. Substitute f(x) for y.
