Unit 8: System Study Guide

1. After graphing y = 3x and y = 3(x - 1), what can be said about the lines? Graph as practice?

• They are parallel.

• They are perpendicular.

• They intersect in one point.

• They intersect in two points.

• (1.4, 4.4)

• (-2, 3)

• (3, 22)

• One solution, because the two lines have the same slope.

• One solution, because the two lines have different slopes.

• No solution, because the two lines have the same slope and different y-intercepts.

• Infinitely many solutions, because the two lines have the same slope and same y-intercept.
