Parallel and Perpendicular Lines Geometry

What slope is perpendicular to:  
m = 5/8

• -5/8

• 5/8

• -8/5

• 8/5

Determine the equation of a line perpendicular to y=-3x-2 and going through the point (9, 2), in slope-intercept form.

Slopes of parallel lines are...

• opposite reciprocals.

• opposites.

• the same.

• always 7.

Which equation is perpendicular to:
 y = -6x +2

• y = 6x +1

• y = 1/6x +4

• y = -6x +3

• y = -1/6x +5

y = 5/7x +2
y = 5/7x - 30
These lines are...

• Parallel

• Perpendicular

• Neither
