Review of slope-intercept form and intercepts

• slope
• y-intercept
• linear
• x-intercept

Answer explanation

In this form, called slope-intercept form, the coefficient of x, which is the value in front of x, is called the slope.

Slope is the rate of change for a linear function. It's the rise over run, or the change of y-values over the change of x-values.

• x-intercept

• y-intercept

• linear

• slope

Answer explanation

In this form, called slope-intercept form, the constant, which is the value with no variable, represents the y-intercept, which is where the linear function intersects the y-axis.

The y-intercept is the ordered pair (0, b).

• 2
• 3
• 5
• 2x 

Answer explanation

Slope is x's coefficient, which means we take only the value in front of x to be the slope.

Answer explanation

The y-intercept is the constant when the linear function is in slope-intercept form.
