Parallel and Perpendicular Equations Through Point Not in Slope Intercept Form

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.

What is the slope of the line that is perpendicular to the line y = -5x + 3?

• 5

• 1/5

• -1/5

• -5

What slope is perpendicular to:  
m = 5/8

• -5/8

• 5/8

• -8/5

• 8/5

The point slope equation of a line that is perpendicular to the line
y= - 4x + 5 and passes through
(5, -6)

• y + 5 = 4 ( x - 5)

• y + 6 = 4 (x + 5)

• y + 6 = 1/4( x + 5)

• y + 6 = 1/4(x - 5)

• y - 4 = 2 (x - 1)

• y - 1 = 4 (x - 4)

• y - 5 = 4 (x - 2)

• y - 5 = - 4 (x - 2)

The  point slope equation of a line that is perpendicular  to the line
 y= - 4x + 5  and passes through 
(5, -6)

• y + 5 = 4 ( x - 5)

• y + 6 = 4 (x + 5)

• y + 6 = 1/4( x + 5)

• y + 6 = 1/4(x - 5)

• I got the last question correct

• I did not check my work

• y - 5 = 2 (x + 4)

• y - 5 = 2 (x - 4)

A line is perpendicular to    y = 2x - 7.
