Slope tells us:

1.   ?    How far away something is.
2.   ?    How high a line is.
3.   ?    How steep a line is.
4.   ?    How smooth a curve is.

For this graph the line has:

1.   ?    No slope
2.   ?    A little slope
3.   ?    A lot of slope

For this graph the line has:

1.   ?    A little slope
2.   ?    A lot of slope
3.   ?    No slope

This line goes down. It's slope is:

1.   ?    Negative
2.   ?    Positive

What is the equation for slope?

1.   ?    slope = Δy/Δx
2.   ?    slope = Δx/Δy
3.   ?    slope = D/T
4.   ?    slope = mx + b

Slope = Δy/Δx
Δy means what?

1.   ?    Change in y.
2.   ?    How much y.
3.   ?    Less than y.
4.   ?    Loss of y.

Slope = Δy/Δx
If Δy means "change in y", how do you find Δy?

1.   ?    Δy = y₂ - y₁
2.   ?    Δy = y₁- y₂
3.   ?    Δy = y₁+ y₂
4.   ?    Δy = y₂

Slope = Δy/Δx
What is the equation for Δx?

1.   ?    Δx = x₁+ x₂
2.   ?    Δx = x₂ - x₁
3.   ?    Δx = x₁- x₂
4.   ?    Δx = x₂

To find slope you need how many points on the line?

1.   ?    3
2.   ?    4
3.   ?    2
4.   ?    1

When calculating slope you need to pick two "good points".
On this graph, which is the "good point"?

1.   ?    C
2.   ?    A
3.   ?    B
4.   ?    D

Which are two good points you could use to find the slope of the line?

1.   ?    C,E
2.   ?    E, G
3.   ?    B,F
4.   ?    B,D
5.   ?    A,G
6.   ?    A,B

After you find two good points, circle the x and y coordinates of those points.
What is the y coordinate for the circled point?

1.   ?    10 s
2.   ?    50 m
3.   ?    12
4.   ?    60 m

What is the x coordinate for the circled point?

1.   ?    10 sec
2.   ?    8 sec
3.   ?    12 sec
4.   ?    6 sec

The only other good point on this graph is:

1.   ?    At (0,0)
2.   ?    At (4, 30)
3.   ?    At (8, 50)
4.   ?    At (2, 10)

Slope = Δy/Δx.
What is Δy for this graph?

1.   ?    10 m
2.   ?    60 m
3.   ?    8 m
4.   ?    40 m
5.   ?    50 m

Slope = Δy/Δx.
Δy = 60 m
What is Δx for this graph?

1.   ?    10 s
2.   ?    40 m
3.   ?    60 s
4.   ?    50 s
5.   ?    8 s

Slope = Δy/Δx.
Δy = 60 m
Δx = 10 s
Calculate the slope.

1.   ?    slope = 40 m
2.   ?    slope = 70 m/s
3.   ?    slope = 50 m/s
4.   ?    slope = 6 m/s
5.   ?    slope = 600 m/s
