Finding Slope

Front

What is the formula to find the slope of a line between two points (x1, y1) and (x2, y2)?

Back

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

Find the slope of the line that passes through the points (2, 4) and (6, 12).

Back

The slope is 2.

Front

Find the slope of the line that passes through the points (-4, 5) and (4, 2).

Back

The slope is -3/8.

Front

Find the slope of the line that passes through the points (6, 7) and (4, 2).

Back

The slope is 5/2.

Front

If the slope of a line is 3, what does this mean in terms of rise and run?

Back

For every 3 units the line rises (vertical change), it runs 1 unit horizontally.

Front

What is the slope of the line that passes through the points (0, 0) and (4, 8)?

Back

The slope is 2.
