Exam 3: Paired Data and Graphing Ordered Pairs

Solve the system by solving one of the equations for or and then use the substitution method. If the lines coincide, answer dependent . If the lines are parallel, answer no solution .

From the graph below, find the x - and y -intercepts for the line. x -intercept = __________ y -intercept = __________

For the equation complete the ordered pair .

Find the x - and y -intercepts for the equation. Then use the intercepts to graph the equation.

Solve the system of linear equations by the elimination method.

For the following line the x -intercept and the y -intercept are both 0, which means the graph of the line will go through the origin, (0, 0). Graph the line by finding a point on it, other than the origin, and then drawing a line through that point and the origin.

Complete the ordered pair for the equation.

Solve the system of linear equations by graphing.

Solve the system of linear equations by elimination.

Graph the line then name the slope and y -intercept by looking at the graph.

Solve the system of linear equations by graphing.

Solve the system by substitution. Substitute the expression in the second equation into the first equation and solve. If the lines coincide, answer dependent . If the lines are parallel, answer no solution .

Solve the system of linear equations by elimination. If the system is dependent or inconsistent , indicate this.

Solve the system by substitution. Substitute the expression in the second equation into the first equation and solve. If the system is dependent or inconsistent , or if there is no solution , indicate this.

Solve the system of linear equations by the elimination method. If the system is dependent or inconsistent , indicate this.

For the equation complete the ordered pairs. ( 0, _____ ), ( _____ , 0 ), ( _____ , -12 )

Solve the system by solving one of the equations for x or y and then use the substitution method. If the system is dependent or inconsistent , or if there is no solution , indicate this.
