Writing Equations from a Graph

Front

What is the slope of a vertical line?

Back

Undefined

Front

What does slope represent in a graph?

Back

Slope represents the rate of change between the y-values and x-values, calculated as rise/run.

Front

What is the slope of a horizontal line?

Back

Zero

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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

Front

What is the meaning of 'rise' in the context of slope?

Back

'Rise' refers to the change in the y-coordinate between two points.

Front

What is the meaning of 'run' in the context of slope?

Back

'Run' refers to the change in the x-coordinate between two points.

Front

What type of slope does a line that goes from the bottom left to the top right have?

Back

Positive slope.
