What is the formula used to calculate the slope of a line?
slope = (rise)/(run)
or m=(y^2-y^1)/(x^2-x^1)
100
if the "run" is 0, what type of slope does the line have?
The slope is undefined.

Graph:
y = -1/2x+4
100
Calculate the slope of the line that passes through (-2,-3) and (2,5).
Slope = 2
100
What is the slope-intercept formula?
y = mx + b
200
If a line goes down 5 units and right 4 units, what is the slope?
slope=
-5/4
200
If the slope of the line is -3/5, how does the line move? Explain using the graph below.
The line moves down 3 units for every 5 units it moves to the right.
200
Graph: y = 3
Explain what kind of slope it is.
The slope is Zero 
200
What is the slope of the line passing through (4,5) and (4,-2)
The slope is undefined because the line is vertical.
200
Identify the y-intercept and slope of the line using the equation
y = -3/4x+5.
y-intercept = 5
m = -3/4
300
What is the slope of a horizontal line?
The slope would be zero
Slope = 0

Find the slope of line that rises 12 units while moving 8 units to the left.
-3/2
300
A line has slope of 3 and passes through the points (0,-2). Write the equation of the line in slope intercept form and graph it.
y = 3x - 2
300
Use the line to find the slope
Slope is Zero
300
A line has a slope of 3 and passes through the y-intercept at 0. What is its equation in slope-intercept form?
y = 2x
400
What does the slope of a line represent?
The steepness of the line or the rate of change
400
A line goes through the origin (0,0) and another point (5,-10). What is the slope?
Slope = -2
400
A line passes through the points (2,-5) and (0,4). Write the equation of the line in sloe-intercept form and graph it. 
y = -9/2x+4
400
Use the two points to find the slope.
slope = 1/3
400
Write the equation of a line with a slope of 3 and a y-intercept of -4. Then, calculate the y-value what x = 2.
y = 3x - 4
When x = 2, the y = 2
500
A line has slope of -2. What does the negative sign mean about the direction of the line?
That the line is going downward from left to right.
500
A line goes through the points (4,2) and (8,2). What is the slope of the line?
Slope = 0
500
Graph: x = 7
Explain the line.
500
Use the line to find the slope and y-intercept. 
y=-2/3-5
500
A line passes through the points (0,-3) ad (2,1). Write its equation in slope-intercept form.
y = 2x - 3
