missing work: Interpreting Graphs

Front

What is a plausible story for a graph showing a student jogging, stopping to tie her shoe, and then continuing at the same pace?

Back

A student was jogging from school to home. She stopped to tie her shoe and take a drink from her water bottle, then continued at the same pace as before.

Front

What are the x- and y-intercepts on a graph?

Back

(5,0), (0,5)

Front

What is a plausible description of a graph showing an object moving away at a constant speed, slowing down, and then returning?

Back

The object began moving away at a constant speed. It continued moving away, but slowed its speed. It then turned around and returned home at a speed that was probably in between the first two speeds.

Front

What is the y-intercept of a graph if it is given as (0,-2)?

Back

(0,-2)

Front

How do you find the slope of a graph?

Back

Slope is calculated as the change in y divided by the change in x.

Front

What does a positive slope indicate on a graph?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate on a graph?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the formula for calculating slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)
