Slope Formula Practice

Front

What is the slope formula?

Back

The slope formula is m = (y2 - y1) / (x2 - x1), where m is the slope, (x1, y1) and (x2, y2) are two points on the line.

Front

What type of slope is represented by a horizontal line?

Back

Zero slope.

Front

What type of slope is represented by a vertical line?

Back

Undefined 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

Find the slope of the line given the points (2, 3) and (4, 7).

Back

m = (7 - 3) / (4 - 2) = 4 / 2 = 2.

Front

Find the slope of the line given the points (-2, -9) and (-1, -3).

Back

m = (-3 - (-9)) / (-1 - (-2)) = 6 / 1 = 6.

Front

If a line has a slope of -5/4, what does this indicate about the line's direction?

Back

The line falls from left to right.

Front

If a line has a slope of 0, what does this indicate about the line?

Back

The line is horizontal.

Front

If a line has a slope of 1, what does this indicate about the line's direction?

Back

The line rises at a 45-degree angle from left to right.
