Question

Using the slope formula for the points (1, 5) and (2, -2), what would the denominator be?

-2 - 5
-2 - 1
2 - 1
2 - 5

Answer 1

1

Explanation:

Moving from (1, 5) to (2, -2), x increases by 1 and y decreases by 7. The slope of the line connecting these two points has the slope m = rise / run = -7 / 1, or just -7.

Alternatively, using the slope formula,

5-[-2] 7

m = ------------ = -------- = (-7/1). The denominator would be 1.

1 - 2 -1

Answer 2

2-1
