# Solve the system of equations by graphing

1. Determine whether the given ordered pair is a solution of the equation.

(-5,1); 2p - 3q = -13

2. For the equation, find the intercepts, Then use the intercepts to graph the equation.

4x - 3y = 12

3. Find the slope of a treadmill.

0.4ft by 5ft

4. Find an equation of the line containing the given point and having the given slope.

(4, -2), m=6

5. Find an equation of the line that contains the given pair of points.

(-6, 1) and (2,3)

6. Determine whether the given ordered pair is a solution of the system of equations. Use alphabetical order of the variables.

(-1, -5); 4r + s = -9, 3r = 2 + s

7. Solve the system of equations by graphing.

x + y = 3, x - y = 1

8. Solve using the substitution method. First solve one equation for one variable.

y - 2x = 0, 3x + 7y = 17

9. Solve using the multiplication principle first. Then add.

7p + 5q = 2, 8p - 9q = 17
