To determine

To check:

The graph of the problems 15-24 using graphing calculator

### Explanation of Solution

Approach:

• Press Y= on the calculator.
• Write the value of y in terms of x.
• Press WINDOW to change the ranges of Xmin, Xmax, Ymin, Ymax according to the equations.
• Press GRAPH.

Calculation:

The graph of the equation is 4x2+8x+16y264y+4=0.

Figure 1

The graph of the equation is 9x236x+4y224y+36=0.

Figure 2

The graph of the equation is x2+8x+9y2+36y+16=0.

Figure 3

The graph of the equation is 4x224x+y2+4y+24=0.

Figure 4

The graph of the equation is 4x2+9y254y+45=0
