Question

Write the equation in slope-intercept form. Then, give the values of m and b.

−2x−4y=28
------------------------------------------------

(Write each value as an integer or a reduced fraction. Do not use decimals or mixed numbers)

y = mx + b

Answer 1

Remember that slope-intercept form is y=mx+b.

First, add 2x on each side to get
`-4y=2x+28`

Then, divide by -4 on each side, and the equation will be
`y=- (1)/(2) x-7`


Looking back in the equation y=mx+b, comparing it to
`y=- (1)/(2) x-7`, we see that
`m=- (1)/(2)` and b = -7.
