Parallel and Perpendicular Lines and Point Slope Formula

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

Which of the following lines is PARALLEL to the graph of y = -6x + 3 and goes through the point (-1,4)?

• y=1/6x +25/6

• y = 1/6x + 4

• y = -6x - 2

• y = -6x + 4

Slopes of parallel lines are...

• opposite reciprocals.

• opposites.

• the same.

• always 7.
