Front

What is the equation of a vertical line?

Back

The equation of a vertical line is of the form x = a, where 'a' is a constant.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

Define the slope of a line.

Back

The slope is defined as rise over run, which is the vertical change over the horizontal change.

Front

What does the slope represent in a linear equation?

Back

The slope represents the rate of change of the dependent variable with respect to the independent variable.

Front

What are x- and y-intercepts?

Back

The x-intercept is the point where the line crosses the x-axis (y=0), and the y-intercept is where it crosses the y-axis (x=0).

Front

How do you find the x-intercept of the equation 3x + 4y = -12?

Back

Set y = 0 and solve for x. The x-intercept is (-4, 0).

Front

How do you find the y-intercept of the equation 3x + 4y = -12?

Back

Set x = 0 and solve for y. The y-intercept is (0, -3).

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What does the term 'rate of change' refer to?

Back

The rate of change refers to how much one quantity changes in relation to another quantity.
