Parallel Perpendicular Point-Slope Form

Identify the slope of a line parallel to the one graphed.

• -7/3

• 3/7

• -3/7

• 7/3

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)

Write the equation in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

• y + 1 = -3(x - 2)

• y + 1 = -3(x + 2)

• y - 1 = 3(x - 1)

• y + 2 = -3(x + 1)

Which of the following lines goes through the point (0, 4) and is parallel to y = 5x - 3?

• y = 1/5x - 3

• y= 5x - 7

• y = 5x + 4

• y = -5x - 3

What slope is perpendicular to:  
m = 5/8

• -5/8

• 5/8

• -8/5

• 8/5

Write the equation of the line PARALLEL to the line y = 4x - 9 that passes through the point (-2, 4)

• y = 4x + 12

• y = -4x -4

• y = -1/4x + 5/2

y = -2/3x + 2 y = 3/2x + 9 These lines are...

• Parallel

• Perpendicular

• Neither

Answer explanation

-2/3 and 3/2 are opposite reciprocals

Write the equation of the line in Point-Slope form that goes through the point (10,5) and has a slope of -3

• y - 5 = -3(x - 10)

• y= -3x + 35

• y + 5= -3(x + 10)

• y= -3x - 35
