Question

Car Rentals charge 20 dollars per day plus a 10 dollar service charge to rent one of its compact cars. The total cost can be represented by the equation y=20x+10 where x is the number of days and y is the total cost
Graph the equation What do the slope and y intercept represent
20x is the slope (days) 10 is the y intercept (service change)

How would I graph it? How much would be spent in 1 day? 30 dollars?

Answer 1

to graph it use any two points on the line

if x = 0 , y = 10
so (0,10) is one point
if x = 532, y = 20*532 + 10 = 10,650
so (532 , 10,650) is a point
take ruler and draw line through those points
(I would suggest using like x = 5 instead of 532)

Answer 2

What would it be for 2 days? Would that be 40 dollars

Answer 3

No
if x = 2
y = 20 * 2 + 10
y = 40 + 10
y = 50

Answer 4

If it was 12 days would it be
y=20*12+10 = 250 dollars?

Answer 5

I thought you only add 10 dollars to the first day
