You will have to set up a system of equations
Percent change = [(45 - 60) / 60] x 100 = -25 % (decrease)
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question the equation of the line is
y = 3x - 4
Comparing with the general equation above
The slope /m = 3
The y intercept / c = - 4
Hope this helps you
