The graph shows a system of equations. The slope of the two lines is (a) . The y-intercept of the green line is (b) and the red line is (c) . The lines are (d)
parallel
perpendicular
zero
undefined
Answer explanation
The slope of both lines is 1, indicating they are parallel. The y-intercept of the green line is 4, and the red line is -7. Since the slopes are equal, the lines do not intersect.

The two tables represent a system of linear equations. Choose the two equations that represent the system.
Answer explanation
The equations y=-\frac{5}{2}x+2 and y=-\frac{9}{2}x+6 are correct as they represent the slopes and intercepts that match the given system of linear equations, while the others do not.

Choose the two equations that represent the system of the equations on the graph.
Answer explanation
The equation x=5 represents a vertical line at x=5. The equation y=-2x+8 is a line with a negative slope that intersects the y-axis at 8. Together, they form the system of equations shown in the graph.
