Writing Linear Equations

Front

What does the letter 'm' represent in the equation y = mx + b?

Back

The slope of the line.

Front

What does the letter 'b' represent in the equation y = mx + b?

Back

The y-intercept of the line.

Front

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

Back

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

Front

What is the slope of a line that rises 3 units for every 4 units it runs?

Back

3/4.

Front

What is the slope of a line that falls 2 units for every 5 units it runs?

Back

-2/5.

Front

Write the slope-intercept form of a line with a slope of 2 and a y-intercept of -3.

Back

y = 2x - 3.

Front

If a line has a slope of 0, what type of line is it?

Back

A horizontal line.

Front

If a line has an undefined slope, what type of line is it?

Back

A vertical line.

Front

What is the slope of the line represented by the equation y = -3x + 4?

Back
