Find b of y = mx + b first using a modified version of the equation.

b = y - mx
b = -1 -(1.2×-3)
b = 13/5 = 2.6

y = 1.2x + 2.6 ← result of substituting values of m and b into y = mx + b

-1.2x + y = 2.6 ← result of subtracting 1.2x from both sides

12x - 10y = -26 ← result of multiplying previous equation by -10

6x - 5y = -13 ← result of dividing previous equation by 2

ANSWER: 6x - 5y = -13

Leona [35]

Answer:

The number of miles Lori drive be 134 miles .

Step-by-step explanation:

Let us assume that the number of miles Lori be x.

As given

Lori rented a car for one day.

The daily rental rate was $12.50 plus 25 cents per mile.

As 1 dollar = 100 cent

1\ cent = \frac{1}{100}\ dollar

25\ cent = \frac{25}{100}\ dollar

25\ cent = 0.25\ dollar

As given

The total cost of her rental was $46.

Than the equation becomes

46 = 12.50 + 0.25x

46 - 12.50 = 0.25x

33.5 = 0.25x

x = \frac{33.5}{0.25}

x = 134 miles

Therefore the number of miles Lori drive be 134 miles .
