Slope Intercept Form

Front

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

Back

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

Front

What does the slope (m) represent in the equation y = mx + b?

Back

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

Front

How do you find the y-intercept from the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0, which is b in the equation.

Front

What is the slope of the line represented by the equation y = 3x + 4?

Back

The slope is 3.

Front

What is the y-intercept of the line represented by the equation y = -2x + 5?

Back

The y-intercept is 5.

Front

How do you graph the equation y = 1/2x - 3?

Back

Start at the y-intercept (0, -3) and use the slope (1/2) to find another point.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

If the slope of a line is 0, what does that tell you about the line?

Back

The line is horizontal.

Front

If the slope is undefined, what does that tell you about the line?

Back

The line is vertical.
