What is the slope of a vertical line?

Back

Undefined

Front

What is the slope of a horizontal line?

Back

0

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

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What is the rate of change in a linear relationship?

Back

The rate of change equals the change in y divided by the change in x.

Front

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

Back

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

Front

What does it mean if a line has a slope of 1/2?

Back

For every 2 units you move right, you move up 1 unit.

Front

What is the slope of the line represented by the equation y = -3x + 5?

Back
