Slope Basics
What formula is used to find slope?
Rise/Run
Which axis usually shows time on a distance–time graph?
x-axis
Find the slope between (0, 0) and (4, 8).
2
An object travels 10 meters in 5 seconds. What is its speed?
2m/s
What does a negative slope tell you about distance over time?
Distance is decreasing
What does slope represent on a distance–time graph?
Speed
Which axis usually shows distance on a distance–time graph?
y-axis
Find the slope between (2, 5) and (6, 5).
0
An object travels 20 meters in 10 seconds. What is its speed?
2m/s
How can you tell which object is moving faster on a graph?
The steeper line
What type of slope goes UP from left to right?
Positive
What does a horizontal line on a distance–time graph mean?
Object is not moving
Find the slope between (1, 2) and (1, 7).
0
If the slope of a distance–time graph is 0, what is the speed?
0m/s (not moving)
Why is a distance–time graph useful?
It shows motion & speed over time
What type of slope goes DOWN from left to right?
Negative
What does a straight slanted line show about motion?
Constant speed
Find the slope between (3, 1) and (5, 5).
2
Which slope shows faster speed: 1 or 3?
3
What does it mean if two lines on a graph are parallel?
They have the same speed
What type of slope does a vertical line have?
Undefined
What does a steeper line on a distance–time graph mean?
Faster Speed
Find the slope between (2, 4) and (6, 6).
1/2
What happens to speed when the slope gets steeper?
Speed increases
What does a flat line tell you about motion?
The object is stopped
