Slope from 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

What does it mean if the slope of a line is undefined?

Back

The line is vertical, meaning it goes straight up and down.

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal, meaning it goes straight across.

Front

Calculate the slope of the line that passes through the points (2, 3) and (4, 7).

Back

m = (7 - 3) / (4 - 2) = 4/2 = 2.

Front

If a line passes through the points (1, 2) and (1, 5), what is the slope?

Back

undefined.

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

m = 3/2.

Front

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

Back

m = (2 - (-1)) / (2 - (-1)) = 3/3 = 1.

Front

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

Back

m = (5 - 0) / (5 - 0) = 1.

Front

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

Back

The line descends from left to right.

Front

Calculate the slope of the line that passes through the points (3, 4) and (3, 8).

Back

undefined.
