Equations of Parallel and Perpendicular Lines

What is the slope of a line that is parallel to the line y = - 1/5 ?

0

what is the slope of a line that is perpendicular to the line y =-1/2 x + 5?

1/2

What is the slope of a line that is parallel to the line y = 3/4x + 2?

3/4

What is the slope of a line that is perpendicular to the line shown on the graph?

4

Which statement is true about the graphs of the two lines y= -8x -5/4 and y= 1/8x + 4/5

The lines are perpendicular to each other because -8 and 1/8 are opposite reciprocals of each other.

Which statement is true about the graphs of the two lines y = -6 and x = 1/6?

The lines are perpendicular to each other because the graph of y = -6 is a horizontal line with a slope of 0, and the graph of x = 1/6 is a horizontal line with a slope that is undefined.

Is AB parallel CB to ? Explain.

Yes, because both lines have a slope of 4/3

Triangle ABC has vertices at A(-2, 3), B(-3, -6), and C(2, -1). Is triangle ABC a right triangle? If so, which angle is the right angle?

Yes, the right angle is angle C.

What is the slope of a line that is perpendicular to the line y = 1?

undefined

What is the equation of the line that is parallel to the line x = -2 and passes through the point (-5, 4)?

x = -5

What is the equation of the line that is parallel to the line y = -1/3x + 4 and passes through the point (6, 5)?

y = -1/3x + 7

What is the slope-intercept form of the equation of the line that passes through the point (-6, 1) and is perpendicular to the graph of 2x + 3y = -5?

y = 3/2x + 10

What is the y-intercept of the equation of the line that is perpendicular to the line y= 3/5x+ 10 and passes through the point (15,-5)?

y= -5/3+20
