Finding slope using Slope triangles

Front

What is the formula for calculating slope?

Back

Slope (m) = Δy / Δx, where Δy is the change in y and Δx is the change in x.

Front

If Δy = 6 and Δx = 3, what is the slope?

Back

Slope = 6 / 3 = 2/1.

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

How do you represent a slope triangle?

Back

A slope triangle is formed by drawing a right triangle between two points on a line, where the vertical leg represents Δy and the horizontal leg represents Δx.

Front

What is the slope of a line that rises 5 units and runs 2 units?

Back

Slope = 5 / 2.

Front

If a line goes down from left to right, what is the sign of its slope?

Back

The slope is negative.

Front

What is the slope of a line that is perfectly vertical?

Back

The slope is undefined.

Front

What is the slope of a line that is perfectly horizontal?

Back

The slope is 0.

Front

If a line has a slope of 3/1, what does this mean?

Back

For every 1 unit the line moves horizontally, it moves up 3 units vertically.
