What is the definition of a linear equation?

Front

What does the slope of a line represent?

Back

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

What is the y-intercept of a linear equation?

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

Front

What is the standard form of a linear equation?

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and 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 can 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-value of the point.

What is a function in terms of linear equations?

Back

A function is a relation where each input (x-value) has exactly one output (y-value). Linear equations are functions if they pass the vertical line test.
