4.5 Equations of Parallel and Perpendicular Lines Revised

What does "m" stand for in the slope formula?

Find the slope given the points (3,2) and (4,7). NOT ON THE PACKET!!!

Slopes of parallel lines are...#10

y = 3x + 2

y = 3x - 3

These lines are...#13

Which of the following lines is PARALLEL to the graph of $$y=6x-3$$  ? NOT ON THE PACKET!!!!

What is the equation of a line parallel to the following line that passes through the given point?

y = -4x + 6 (2, -1) #3

2Which is the equation of the line that is PARALLEL to the graph of y = 5x + 7 and has a y-intercept at (0, -2)? #2 on CW and #2 on HW

HINT: PLUG (0,-2) AND THE PARALLEL SLOPE INTO y=mx+b. SOLVE FOR b AND REWRITE THE EQUATION IN y=mx+b.

Slopes of perpendicular lines are...#11

y = -2/3x + 2

y = 3/2x + 9

These lines are...#5

Write an equation for a line perpendicular to

y = -5x + 3 through (-5, -4). #15
