Graphing linear equations using slope intercept form

Front

What does 'b' represent in the equation y=mx+b?

Back

y-intercept

Front

What is the first step after graphing the y-intercept when graphing a linear equation?

Back

Find the slope and start with your rise (up or down) then run (left or right).

Front

In the equation y=mx+b, what does 'm' represent?

Back

slope

Front

How do you determine the slope from a graph?

Back

The slope is determined by the ratio of the rise (change in y) to the run (change in x).

Front

What is the slope of the equation y=4x+3?

Back

4

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 can you identify the y-intercept on a graph?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What does a positive slope indicate about a linear graph?

Back

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

Front

What does a negative slope indicate about a linear graph?

Back

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

Front

If a line has a slope of 0, what does that mean?

Back

The line is horizontal and does not rise or fall as x changes.
