40 PIONTS FOR ANSWERING 2 Q'S, I WILL PICK BRIANLISET

my equation for Q 7: C=2.7m+1.95

8. For the Raleigh company write an equation in point-slope form to represent the amount charged, C, for m number of miles for the company in Raleigh, NC.

9. Write an equation in standard form to represent the amount charged, C, for m number of miles for the company in Raleigh.

Answer 1

8.m = ∞

9.
`m=(20c-39)/(54)`

Explanation:

8.The equation is a vertical line, so the slope is ∞

so the answer for 8. is m = ∞

9.Switch sides:

2.7m + 1.95 = c

Multiply both sides by 100:

2.7m · 100 + 1.95 · 100 = c · 100

Refine:

270m + 195 = c · 100

Move 195 to the right side so it would be: 270m = c · 100 - 195

And now Divide both sides by 270

`(270m)/(270)` =
`(c*100)/(270)` -
`(195)/(270)`

And now all that's left is to Simplify it

so the answer for answer 9. is
`m=(20c-39)/(54)`
