Finding Slope from Graphs

The video tutorial explains how to find the slope from a graph. It introduces the concept of slope as the ratio of the change in y (rise) over the change in x (run) on a coordinate grid. The tutorial provides four problems, demonstrating how to calculate slope using clear points on a graph, including cases with negative slopes and verifying consistency with different points. The video emphasizes the importance of selecting points at clear intersections for accurate slope calculation.

What is the vertical axis called in a coordinate grid?

• Y-axis

• X-axis

• W-axis

• Z-axis

What does the horizontal axis measure?

• Side to side

• Circular

• Up and down

• Diagonal

What is another term for the change in y?

• Run

• Rise

• Slope

• Shift

In the context of slope, what does 'run' refer to?

• Vertical movement

• Horizontal movement

• Diagonal movement

• Circular movement

If a point moves up 4 units and to the right 3 units, what is the slope?

• 4/3

• 1/3

• 3/4

• 3/1

Why is it important to choose points that lie on clear intersections?

• To avoid confusion

• To accurately determine the slope

• To make the graph look neat

• To simplify calculations

What is the slope if the change in y is -5 and the change in x is 1?

• -1

• 1

• -5

• 5

If the change in y is 2 and the change in x is 4, what is the simplified slope?

• 4/2

• 1/2

• 2/4

• 2/1

Does the slope change if different points on the same line are used?

• Yes

• No

• Sometimes

• Depends on the points

What do you need to determine to find the slope from a graph?

• Neither change in y nor change in x

• Only change in x

• Only change in y

• Change in y and change in x
