y=6x+2

y=-6x-2

• Parallel

• Perpendicular

• Neither

Multiple Select

Select all that are true.

• Parallel lines never intersect.

• Perpendicular lines never intersect.

Multiple Choice

Which equation represents the equation of the line passing through the point A, parallel to the given line?

Step 1: find the slope of given line

Step 2: Substitute values for y=mx+b with found slope "m" and given point (x,y)

• y = -1/3x + 2

• y = -3x + 7

• y = 3x + 1

• y = -1/3x + 7/3

Multiple Choice

Which represents the equation of the line passing through the point A, perpendicular to the given line?

• y = -1/3x + 2

• y = -3x -1

• y = 3x -1

• y = -1/3x + 7/3
