Question

1) Determine the type of boundary line and shading for the graph of the inequality -5x - y ≤-2

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

the solid line under the duckbill tells us we at least want a solid line on the graph

Answer 2

since its asking if the origin should be included; plug in the x and y values of the origin to see if it makes a true of false statement;

true means we keep it; false we reject it
