Linear Equation Parallel and Perpendicular

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.

Write an equation of a line perpendicular to
y = 2/7x - 5 through (2, -3)

• y = -7/2x + 4

• y = -4x - 7/2

• y = 4x - 7/2

• y = 7/2x + 4

y = 5/7x +2
y = 5/7x - 30
These lines are...

• Parallel

• Perpendicular

• Neither

Gregory graphed the equations y = -3x + 5 and y = 2x - 5. These lines are ​ ​ (a)   because their slopes are ​ (b)   .

• perpendicular

• intersecting at an angle that is not 90 degrees
