Identify Slope and Y-Intercept from an Equation

Front

What is the y-intercept in the equation y = mx + b?

Back

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

Front

How do you identify the slope from the equation y = mx + b?

Back

The slope is represented by m in the equation, indicating the rate of change of y with respect to x.

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 = 4x + 1?

Back

The slope is 4.

Front

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

Back

The y-intercept is 2.

Front

In the equation y = 0.5x - 1, what is the slope?

Back

The slope is 0.5.

Front

What is the y-intercept of the equation y = -x + 7?

Back

The y-intercept is 7.

Front

If the slope of a line is 0, what does this mean about the line?

Back

A slope of 0 means the line is horizontal.

Front

If the slope of a line is undefined, what does this mean about the line?

Back

An undefined slope means the line is vertical.
