Front

What are the x- and y-intercepts for the equation 5x - 3y = 15?

Back

(3, 0) and (0, -5)

Front

What can be said about the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

Is the line represented by the equation y = 10 vertical, horizontal, or neither?

Back

Horizontal.

Front

Write the equation of the line with a slope of 3/5 that passes through the y-intercept of -1.

Back

y = (3/5)x - 1.

Front

What slope is perpendicular to m = 5/8?

Back

-8/5.

Front

Define a linear function.

Back

A linear function is a function that graphs to a straight line, represented by the equation y = mx + b.

Front

What does the slope (m) represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0, represented by b.

Front

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

Back

Set y = 0 and solve for x.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.
