Front

What is the slope of a line perpendicular to a line with slope m = 5/8?

Back

-8/5

Front

What is the equation of a line in slope-intercept form?

Back

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

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

How do you determine if two lines are perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

What is the slope of the line represented by the equation y = -x - 3?

Back

The slope is -1.

Front

What does the y-intercept represent in a linear function?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What is the slope of the line represented by the equation y = 4x + 2?

Back

The slope is 4.

Front

Are the lines y = -1/4 x - 5 and y = 4x + 2 parallel, perpendicular, or neither?
