What is a linear function?

Back

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-coordinate with respect to the x-coordinate. It indicates how steep the line is.

Front

How do you find the x-intercept of a linear equation?

Back

Front

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

Back

Front

What is an equivalent equation?

Back

An equivalent equation is an equation that has the same solution as another equation, even if it is expressed in a different form.

Front

How do you convert the standard form of a linear equation to slope-intercept form?

Back

Front

What is the significance of the y-intercept in a linear function?

Back

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts, meaning they will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1, meaning they intersect at a right angle.

Front

How do you determine if a point lies on a line represented by an equation?

Back

To determine if a point (x, y) lies on a line, substitute the x-value into the equation and see if the resulting y-value matches the y-coordinate of the point.
