Ravi drove 648 miles in 9 hours. At the same rate,how long would it take him to drive 792 miles ?

Ravi will drive 792 miles in 11 hours

Step-by-step explanation:

Ravi drove 648 miles in 9hours, let the missing number of hours be represented by x.

Therefore,

648 miles = 9 hours

792 miles = x hours

Find x.

To find x, we cross multiply:

648x = 9 x 792

648x = 7128

Divide both sides by 648

x = 11

Therefore, ravi will drive 792 miles in 11 hours.

y = 2x - 2

Step-by-step explanation:

y2 - y1 / x2 - x1

6 - 2 / 4 - 2

4 / 2

=2

y = 2x + b

2 = 2(2) + b

2 = 4 + b

-2 = b
