Graphing Lines

Front

What is the slope-intercept form of a line?

Back

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

Front

What do you graph first when using slope-intercept form?

Back

You graph the y-intercept (b) first.

Front

How do you find the second point when graphing a line?

Back

Use the slope (m) to find the second point from the y-intercept.

Front

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

Back

The slope is 1/2.

Front

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

Back

The y-intercept is -1.

Front

What is the y-intercept in the equation y = 6x - 4?

Back

The y-intercept is -4.

Front

How do you calculate slope using rise and run?

Back

Slope = rise/run.

Front

What is the slope of a line if the rise is -5 and the run is 3?

Back

The slope is -5/3.

Front

Which equation represents a line with a slope of 1/4 and a y-intercept of 2?

Back

The equation is y = 1/4x + 2.

Front

What does the slope of a line represent?

Back

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