Graphing Lines (SS)

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

If m=3 and b=6, what is the slope-intercept equation?

Back

y = 3x + 6

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope is 2.

Front

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

Back

The slope is -1/2.

Front

What does a slope of zero indicate about a line?

Back

A slope of zero indicates a horizontal line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

How do you graph the equation y = x - 1?

Back

Start at (0, -1) on the y-axis and use the slope of 1 to rise 1 and run 1 to the right.

Front

What is the y-intercept in the equation y = 3x + 2?

Back

The y-intercept is 2.
