Back

x = -1

Front

What is the equation of a vertical line that passes through the point (2, 0)?

Back

Front

What is the equation of a horizontal line that passes through the point (0, 2)?

Back

y = 2

Front

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

Back

y = -1

Front

What is the slope-intercept form of a line with a slope of -3 and a y-intercept of -2?

Back

y = -3x - 2

Front

What does the slope of a line represent?

Back

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

Front

What is the y-intercept of the line represented by the equation y = 2x + 3?

Back

The y-intercept is 3.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the slope of a line that rises 4 units for every 2 units it runs?

Back

The slope is 2.

Front

What is the general form of the equation of a line?

Back

Ax + By + C = 0, where A, B, and C are constants.
