Question

Determine the type of boundary line and shading for the graph of the inequality -2x - y >= -8

Dashed line with shading on the side that includes the origin.

Solid line with shading on the side that does not include the origin.

Dashed line with shading on the side that does not include the origin.

Solid line with shading on the side that includes the origin.

Answer 1

dashed shading and shading on the side that includes the origin

Answer 2

can u show work just to be sure???

Answer 3

you know it is dashed because it is not <= or>=

Answer 4

to test the origin replace the x and y intercepts to see if it works

Answer 5

so it becomes -y=2x-8
replace the y and x woth 0 to see if it is true 0 is bigger than -8 so it is true!
