x-intercept = -19
y-intercept = 380
Given

Part A
To find the x-intercept, we set y=0
The x intercept is the point where the line crosses the x axis. At this point y = 0

Part B
To find the y-intercept, we set x=0
The y- intercept is the point where the line crosses the x-axis.
At this point x= 0

Part C
Graph of f(x)=380-20x
