Finding Slope from Two Points and a Graph Review

Front

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

Back

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

Front

Find the slope of the points (12,-2) and (4,-6).

Back

1/2

Front

Find the slope of the points (-2,3) and (4,-5).

Back

-4/3

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

Front

What is the slope of a horizontal line?

Back

0

Front

What is the slope of a vertical line?

Back

Front

How do you interpret the slope in a real-world context?

Back

The slope represents the rate of change between two variables.

Front

Find the rate of change for the points (1, 2) and (3, 4).

Back

1

Front

If the slope of a line is -1/3, what does this tell you about the relationship between x and y?

Back

For every 3 units increase in x, y decreases by 1 unit.
