Finding Slope Post Test

Front

What is the formula to find 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

Find the slope of the points (2, 3) and (5, 11).

Back

The slope is (11 - 3) / (5 - 2) = 8 / 3.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

If the slope of a line is zero, what does this mean?

Back

A slope of zero means the line is horizontal.

Front

If the slope of a line is undefined, what does this mean?

Back

An undefined slope means the line is vertical.

Front

Back

The slope is 3.

Front

What type of relationship does a line with a slope of 1 indicate?

Back

A slope of 1 indicates a proportional relationship.

Front

Find the slope of the points (4, 5) and (4, 9).

Back

The slope is undefined because the x-coordinates are the same.

Front

Back

The slope is -1/2.
