Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

Solve for x: 2x - 3 + 4x = 27

Back

x = 5

Front

What does the line y = 6 represent?

Back

It represents a horizontal line where all y-values are equal to 6.

Front

What does the line x = 3 represent?

Back

It represents a vertical line where all x-values are equal to 3.

Front

What is the slope of the line represented by the equation y = (-5/2)x - (3/2)?

Back

The slope is -5/2.

Front

What is the y-intercept of the equation y = (-5/2)x - (3/2)?

Back

The y-intercept is -3/2.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) for the function.

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed.
