Point Slope Parallel Perpendicular to Standard Form

Perpendicular lines have ________ slopes

• same

• opposite

• opposite reciprocal

• reciprocal

What slope is perpendicular to:  
m = 5/8

• -5/8

• 5/8

• -8/5

• 8/5

What slope is perpendicular to:  
m = 3

• -3

• -1/3

• 1/3

• 3

• y - 5 = 2 (x + 4)

• y - 5 = 2 (x - 4)

Given the point (5, -2) and a slope of 1, write the equation of the line in point-slope form.

• -3

• 1

• -1

• 3

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)

• y - 4 = -1/4(x + 7)

• y + 7 = 4(x - 4)

• y - 7 = -1/4(x - 4)

• y - 4 = 2 (x - 1)

• y - 1 = 4 (x - 4)
