Answer 1

Answer:

B.

Step-by-step 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:

$0=-2x-4$

$0+4=-2x-4+4$

$4=-2x$

$\frac{4}{-2}=\frac{-2x}{-2}$

$-2=x$

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.
