Answer:

<u>Given</u>

  • Equation 5x - y = 12

and

  • Inequality 5x - y > 12

<em>See the graphs attached</em>

To draw the graphs follow the rules we described in the previous questions.

  • 1. Identify x-intercept and y-intercept and connect them to have the line.
  • 2. Shade the region above or below the line for the inequality.

We see the only difference the expressions have is the equation or inequality symbols.

  • Equation symbol means the graph of the equation is a line.
  • Inequality symbol means the graph of this is a region above the same line, in our case the line is not a part of the covered region because it is "<".

We can state that the inequality excludes the line and includes only the region above the same line.
