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 .

Draw a straight line that passes through the points (3, 4) and (3, -4). Is the graph of (3, 0) on this line?

Find y if the line through (1, 1) and (2, y ) has a slope of 3.

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

Solve the system using the substitution method. If the lines coincide, answer dependent . If the lines are parallel, answer no solution .

Graph the inequality.

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.

Complete the given ordered pairs for the equation.

Graph the line that passes through the point (2, 9) and has an y -intercept of 7. What is the x -intercept of this line?

Find the slope of the line through the pair of points (1, - 2), (3, 5). Plot the pair of points, draw a line through them, and indicate the rise and run in the graph.

Graph the line with the given slope and y -intercept b .

Graph the solution set.
