Finding Slope Review

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a negative slope indicate about a line on a graph?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, meaning the line goes downward from left to right.

Front

What does a positive slope indicate about a line on a graph?

Back

A positive slope indicates that as the x-values increase, the y-values also increase, meaning the line goes upward from left to right.

Front

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

Back

A slope of 0 indicates a horizontal line.

Front

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

Back

An undefined slope indicates a vertical line.

Front

Calculate the slope between the points (2, 3) and (4, 7).

Back

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

Front

Calculate the slope between the points (1, 2) and (3, 4).

Back

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

Front

What is the slope of the line that passes through the points (0, 5) and (6, 2)?

Back

The slope is m = (2 - 5) / (6 - 0) = -3 / 6 = -1/2.

Front

Back

The slope is negative because the coefficient of x is -3.
