Slope Basics Review

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 type of slope is represented by a horizontal line?

Back

Zero slope.

Front

What type of slope is represented by a line that rises from left to right?

Back

Positive slope.

Front

What type of slope is represented by a line that falls from left to right?

Back

Negative slope.

Front

What does an undefined slope indicate?

Back

A vertical line.

Front

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

Back

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

Front

If a line has a slope of 6, what does this mean?

Back

For every 1 unit increase in x, y increases by 6 units.

Front

What is the slope of a line that does not change in y as x changes?

Back

Zero slope.

Front

If a line has a slope of -3, what does this indicate?

Back

For every 1 unit increase in x, y decreases by 3 units.

Front

What is the slope of a line that is vertical?
