Slope - Equations, Graphs, Tables and Two points

Front

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

Back

m = (y2 - y1) / (x2 - x1)

Front

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

Back

m = 2

Front

Determine the slope of the line that passes through the points (1, 2) and (3, -4).

Back

m = -3

Front

What is the slope of a horizontal line?

Back

0

Front

What is the slope of a vertical line?

Back

Undefined

Front

If the slope of a line is positive, what does that indicate about the line's direction?

Back

The line rises from left to right.

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

The line falls from left to right.

Front

What does a slope of 1 indicate about the line?

Back

The line rises at a 45-degree angle.

Front

What does a slope of -1 indicate about the line?

Back

The line falls at a 45-degree angle.

Front

If a line has a slope of 3/2, what does this mean in terms of rise over run?

Back

For every 2 units moved horizontally (run), the line rises 3 units.
