GRAPHING SLOPE EQUATIONS

Front

What is another name for the slope?

Back

Constant, Unit Rate, Rate of Change, Rise/Run.

Front

Define slope in mathematical terms.

Back

Slope is the ratio of the rise (vertical change) to the run (horizontal change) between two points on a line.

Front

What does a positive slope indicate?

Back

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

Front

What does a negative slope indicate?

Back

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

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

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

Back

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

Front

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

Back

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

Front

What does the 'b' represent in the slope-intercept form?

Back

The 'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

If a line has a slope of 2, what does this mean?

Back

For every 1 unit increase in x, the y-value increases by 2 units.
