F(x) = x - 0.15x
sale = original - 0.15(original)
y = 0.85x
Answer:

Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to

where
m is the slope
b is the y-intercept
In this problem we have

substitute the given in the equation

Solve for b

subtract 18 both sides


therefore
The linear equation in slope intercept form is equal to

Answer:
Make x 0 and y 3
Step-by-step explanation:
0 multiplied by 2 is 0
-3 multiplied by 3 is -9
0-9 = -9
