Front

What is the slope of a line parallel to m = 3/4?

Back

3/4

Front

What do the lines y = 6x + 2 and y = -6x + 2 represent?

Back

Neither parallel nor perpendicular.

Front

Find the slope of the line represented by the points (1, 2) and (3, 0).

Back

-1

Front

What is the proper range for the function y = x^2?

Back

y ≥ 0

Front

How do you find the rate of change in a linear function?

Back

Change in y over change in x, rise over run, or subtract y coordinates over subtract x coordinates.

Front

What is the definition of slope in a linear equation?

Back

The ratio of the rise (change in y) to the run (change in x).

Front

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

Back

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

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

The line is vertical.

Front

How can you determine if two lines are perpendicular?

Back

Their slopes are negative reciprocals of each other.
