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

Write an equation that is parallel to 
y = -2x + 4
and runs through the point (-3, 2 )

• y = - 2x - 4

• y = - 2x - 8

• y = - 2x + 4

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

• Parallel

• Perpendicular

• Neither

• The same line

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

• Parallel

• Perpendicular

• Neither
