Graphing Using Slope-Intercept Form

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 slope (m) represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x; it indicates how steep the line is.

Front

What does the y-intercept (b) represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

How do you find the slope from the equation y = 3x + 5?

Back

The slope (m) is 3.

Front

How do you find the y-intercept from the equation y = -2x + 4?

Back

The y-intercept (b) is 4.

Front

What is the slope of the line represented by the equation y = -x + 2?

Back

The slope (m) is -1.

Front

What is the y-intercept of the line represented by the equation y = 1/2x - 1?

Back

The y-intercept (b) is -1.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates a vertical line.

Front

Graph the equation y = 2x + 1. What is the slope and y-intercept?

Back

Slope: 2, Y-intercept: 1.
