Can you help me? Please explain how you got it!

Answer 1

B.

Explanation:

First we must find the x and y intercepts for y = -2x - 4. The y-intercept is -4, since it is b in y = mx + b, but you can also find it by plugging in zero for x:

`y = -2(0) - 4 = 0 -4=-4`

The x-intercept is found by plugging in zero for y:

`0=-2x-4`

`0+4=-2x-4+4`

`4=-2x`

`(4)/(-2)=(-2x)/(-2)`

`-2=x`

The graph with an x-intercept of -2 and a y-intercept of -4 is C. Also, less than inequalities have the shading underneath the line, so we definitely know C is the answer.
