Write the equation in slope-intercept form, y - mx + b. Write the equation of the line that passes through the points (3, 4) and (7, 20),Explanation / Answer
(a)
C = 80h + 45
For vertical intercept, h = 0, put that in the equation
C = 80*0 + 45 = 45
(h,C) = (0,45)
The fixed cost to rent a backoe is $45, and additionaly for every hour it is kept, there will be additional charge.
But the $45 is fixed.
(b)
Horizontal intercept is the point at which the y-coordinate is 0.
C = 0 = 80h + 45
h = -45/80 = -9/16
(h,C) = (-9/16,0)
Renting a backhoe for (-9/16 hours will cost 0.
What it really means is that instead of renting the backhoe, you actually give out your backhoe for 9/16 hours, you will get 0 in return. Anyway the concept of negative time is not applicable for this equation.
