Find the missing point- Slope

Front

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

Back

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

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 zero indicate about a line?

Back

The line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

The line is vertical.

Front

Calculate the slope of the line that passes through the points (2, 3) and (5, 11).

Back

Slope = (11 - 3) / (5 - 2) = 8 / 3.

Front

What is the slope of the line that passes through the points (1, 2) and (4, 5)?

Back

Slope = (5 - 2) / (4 - 1) = 3 / 3 = 1.

Front

Find the missing value x if the slope of the line through (x, 4) and (2, 8) is -2.

Back

x = 0.

Front

What is the slope of the line that passes through the points (3, 7) and (3, 2)?

Back

Slope is undefined.

Front

If a line has a slope of -4/5, what type of slope is it?

Back

Negative slope.
