The sale price of a new refrigerator is $648 and sales tax is figured at 0.10 times the price. What is the total amount paid for the refrigerator?

$712.80

Step-by-step explanation:

648×0.10=64.8

648+64.8=712.8

The answer to your question is the letter B.    y = -1/2x - 1

Step-by-step explanation:

Data

A (-6, 2)

slope = m = -1/2

Formula

             y - y1 = m(x - x1)

x1 = -6     y1 = 2

Substitution

            y - 2 = -1/2(x + 6)

Expand

            y - 2 = -1/2x - 6/2

Simplify

            y - 2 = -1/2x - 3

Solve for y

                 y = -1/2x - 3 + 2

Result

                 y = -1/2x - 1
