Question

The graph below shows the solution to a system of inequalities:

Solid line joining ordered pairs 0, 3.75 and 15, 0. Shade the portion of the graph above the line in the first and second quadrant

Which of the following inequalities is modeled by the graph?

x + 4y ≥ 15; y ≥ 0
x − 4y ≥ 15; y ≥ 0
x + 4y ≤ 15; y ≥ 0
−x − 4y ≥ 15; y ≥ 0

Answer 1

Answer 2

Please enclose within parentheses the numbers representing the two given points:

Solid line joining ordered pairs 0, 3.75 and 15, 0

should be ordered pairs (0, 3.75) and (15, 0).

Please actually plot these two points, now. Familiar with the Draw utility?
