Find the equation for the linear function that passes through the points ( see photo)

Answer:f(x) = (-4/5)*x + 4Step-by-step explanation:The line which passes through these points will decrease y by 12 for every x increase of 15. This is the same as decreasing y by 4 for every x increase of 5. This means the slope (rise over run) is -4/5. If this is applied to the first point to find what y is at 0, then the point (0, 4) is on the line.This means that f(x) = (-4/5)*x + 4
