Front

What is the slope of a vertical line?

Back

Undefined

Front

What is the slope of a horizontal line?

Back

Zero

Front

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

Back

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

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 the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

If a line has a slope of 1/2, what does this mean?

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 + 2?

Back

3

Front

How do you convert the equation y = -2x + 5 to slope-intercept form?

Back

It is already in slope-intercept form.

Front

What is the y-intercept of the line y = 4x + 3?

Back

3

Front

What is the equation of a line with a slope of -1 that passes through the point (0, 2)?

Back

y = -x + 2
