Bill wants to rent a car. rental company a charges $45 plus $1 per mile driven. rental company b charges $25 plus $2 per mile driven. after how many miles driven will the price charged by each company be the same?

20 miles

Step-by-step explanation:

I set this up as a linear equation:

45 + x = 25 + 2x

1. subtract x from both sides

45 = 25 + x

2. subtract 25 from both sides to isolate the variable

20 = x

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
