On completing the statement, we get,

"When graphing an inequality in two variables, if the inequality is strict use dashes ; if the inequality is nonstrict use a solid mark."

Step 1. Given information.

Consider the given statement,

"When graphing an inequality in two variables, if the inequality is strict use ___ ; if the inequality is nonstrict use a ___ mark."

For example, consider the inequality while graphing we would consider only those points which are below the line.

But if the inequality is of the type then while graphing we would not only consider the points below the line but also the points on the line.

Step 2. Complete the sentence.

On completing the given sentence,

"When graphing an inequality in two variables, if the inequality is strict use dashes ; if the inequality is nonstrict use a solid mark."
