The inequality is , where x is the midterm score and y is the final exam score.
The graph of the inequality is the shaded region, so every point in the shaded region satisfies the inequality.
The graph of the equation is the boundary of the region. Since the inequality
, the boundary is drawn as a solid line to show that points on the line satisfy the inequality.
To determine which half-plane to be shaded use a test point in either half-plane.
\Substitute the value of in the original inequality.
.
Since the above statement is true, shade the region that contains point .
Therefore Rosa will get an A, she scores 85 on the midterm and 95 on the final.
Yes, Rosa will get an A then she scores 85 on the midterm and 95 on the final.
