Algebra1 Period 02 Chapter 3 SLOPE FINAL REVIEW

Front

What is the formula to calculate the slope of a line passing through two points?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

Calculate the slope of the line passing through the points (5, 8) and (−4, 6).

Back

The slope is (6 - 8) / (−4 - 5) = -2 / -9 = 2/9.

Front

What is the slope of the line passing through the points (−3, −2) and (3, 4)?

Back

The slope is (4 - (-2)) / (3 - (-3)) = 6 / 6 = 1.

Front

What is the slope of a line perpendicular to a line with a slope of 2?

Back

The slope of a line perpendicular to a line with slope m is -1/m. Therefore, the slope is -1/2.

Front

Calculate the slope of the line passing through the points (1, 4) and (5, 8).

Back

The slope is (8 - 4) / (5 - 1) = 4 / 4 = 1.

Front

What is the slope of a line parallel to a line with a slope of 2?

Back

The slope of a line parallel to a line with slope m is the same, so the slope is 2.

Front

Calculate the slope of the line connecting the points (3, 7) and (7, 15).

Back

The slope is (15 - 7) / (7 - 3) = 8 / 4 = 2.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

If a line has a slope of -1, what does this indicate about its direction?

Back

A slope of -1 indicates that the line decreases at a 45-degree angle from left to right.
