1 answer:
Answer:
Step-by-step explanation:
Slope of line through the three points is -3.
Slope of any perpendicular through the line is ⅓.
(0,1) is one of the points on the line, so the y-intercept is 1.
Slope-intercept equation for line of slope ⅓ and y-intercept 1:
y = ⅓x+1

Answer:
4 hours of rental
Step-by-step explanation:
y1 = 20 + 13.5x
y2 = 6 + 17x
20 + 13.5x = 6 + 17x
20 - 6 = 17x - 13.5x
14 = 3.5x
x = 4
Costs y1 and y2 are equal on renting for 4 hours
