Question

Which correctly describes how the graph of the inequality 4x - 2y > 20 is shaded ?

Above the solid line

Below the solid line

Above the dashed line

Below the dashed line

Answer 1

since we have a > sign rather than a ≥ the graph is a dashed line (eliminating choices 1 and 2)

now, to determine whether to shade above or below, solve the inequality for y. if you get something like

y < (something) shade below, and if you get y > (something) shade above the line.

let me know if you're still confused or want to check your solution.
