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)

• (3, -2)

• 
• 
• 
• 

• Infinitely Many Solutions

• No Solution

• (4, -1)

• (-1, 4)

• (2, 0)

• (3, -1)

• (0, 2)

• (6, 1)

• 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.
