Th Graphing from Slope-Intercept Form

Front

What is the slope in the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

In the slope-intercept form, what does the b represent?

Back

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

Front

How do you find the rise/run from a slope of -2?

Back

The rise/run for a slope of -2 is -2/1.

Front

What is the first step when graphing from slope-intercept form?

Back

First, graph the b value on the y-axis.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line is decreasing from left to right.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line is increasing from left to right.

Front

How do you graph the equation y = 2/3x - 4?

Back

Start at (0, -4) on the y-axis, then use the slope 2/3 to find another point.

Front

What is the graph of the equation x = 3?

Back

The graph of x = 3 is a vertical line that crosses the x-axis at 3.

Front

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

Back

The formula for slope is m = (y2 - y1) / (x2 - x1).
