Question

Which equation represents a line with a slope of -2?

a. y = 2x – 1
b. y = -2x +-1
c. y = x - 2
d. y = -x + 2

Answer 1

y= mx+b

slope is also m

b= y-intercept

Answer: b. y = -2x +-1

Answer 2

`\huge\boxed{\text{B}}`

Slope-intercept form is
`y=mx+b`, where
`m` is the slope and
`b` is the y-intercept.

In this case, we need to look for the equation with
`m=-2`.

The only equation with a slope of
`-2` is
`\boxed{y=-2x+(-1)}`.
