Review of SLOPE
parallel & perpendicular lines
2
Multiple Choice
Rewrite this equation in slope intercept form (y = mx + b):
9x + 3y = -6
3y = 9x -6
y = -3x -2
y = -9x - 6
y = -3x +2
3
Multiple Choice
Rewrite this equation in slope intercept form (y = mx + b):
6x - 2y = 10
2y = 6x - 10
y = -3x - 5
y = 3x - 5
y = -3x + 5

Multiple Choice
Write a linear equation in slope intercept form of a line with a slope of 12 and y intercept of 10
y=12x-10
y=10x+12
y=12x+10
x=10x-12
6
slope is the rate of change
slope = "rise over run"
slope = vertical change divided by horizontal change
m=(y2-y1)/(x2-x1)
Remember Slope?

8
Identify the coordinates for 2 points on the line
Count the vertical distance (up+ or down-) from first point to second
Count horizontal "blocks" (left- or right+) from first point to second
Write the slope as the ratio of vertical/horizontal

Identify one point as (x1, y1) and the second as (x2, y2)
Find the vertical distance (y2-y1)
Find the horizontal distance (x2-x1)
Write the ratio of vertical/horizontal distances (you might have to reduce)

Types of Slopes

Multiple Select
Which of the following have UNDEFINED SLOPES? (Select ALL that Apply)
y=3
x=3
19
Multiple Choice
What kind of slope does the graph have?
Positive
Negative
0
Undefined
20
Parallel lines lie in the same plane and never intersect.
What do you notice when you compare the slopes of two parallel lines?
Parallel Lines
21
Multiple Choice
opposite reciprocals.
opposites.
identical.
always 7.
22
Remember PERPENDICULAR Lines intersect to FORM RIGHT ANGLES
Slopes are OPPOSITE SIGNS and "FLIPPED"
Perpendicular Lines
23
Multiple Choice
y = 3x - 3
These lines are...
Parallel
Perpendicular
Neither
The same line
24
Multiple Choice
opposite reciprocals.
opposites.
identical.
always 7.

Multiple Choice
y = 5/7x +2
y = 5/7x - 30
These lines are...
Parallel
Perpendicular
Intersect
29
Multiple Choice
y = 6x + 2
y = -6x + 2
These lines are...
Parallel
Perpendicular
Intersecting (neither parallel nor perpendicular)
30
Be careful!
Lines that do not meet BOTH opposite signs AND reciprocals are merely Intersecting (But NOT perpendicular)
31
Multiple Choice
y = -1/3x - 5
y = 1/3x + 2
Parallel
Perpendicular
Neither
32
Multiple Choice
Are these two lines parallel, perpendicular or neither?
y = -1/4 x - 5
y = 4x + 2
Parallel
Perpendicular
Neither
33
Multiple Choice
Find the slope PARALLEL to a line that passes through the points (4, 2)
and (– 8, 5)
m∥=34
m∥=−123
m∥=123
m∥=−312

Multiple Choice
Find the slope PERPENDICULAR to a line that passes through the points (4, 2)
and (– 8, 5)
m⊥=312
m⊥=−312
m⊥=123
m⊥=−123
