Write an equation  
m = -1/2 through (-2, 4)

• y = -3/2x + 3

• y = 3/2x + 3

• y = -1/2x + 3

• y = 3x - 3/2

Given the equation in point slope form, y - 1 = 3(x + 2), which of the following represents the slope and a point on the line.

• m = 3;  (-2, 1)

• m = 1;  (3, 2)

• m = 3;  (2, 1)

• m = 3;  (-2, -1)

Which statement correctly describes the graph?

• The lines are parallel because they have different slopes.

• The lines are NOT parallel because they have different y-intercepts.

• The lines are parallel since they have the same slope and different y-intercepts.

• The lines are perpendicular.

Are the following equations parallel or not? HINT: Solve the second equation for y so that it is in y=mx + b form. y = 2x - 5 and 4x + 2y = 10

• Yes, they are parallel

• No, they are not parallel
