Question

What is the slope of the line which contains the ordered pairs (2, 1) and (-3, 5)?

a. -5/4
b. -4
c. -1/4
d. -4/5

Answer 1

d. -4/5

Explanation:

When using the equation m = y2 - y1 / x2 - x1, we get m = 5-1 / -3-2.

Simplified: m = 4/-5.

The negative can be placed on the numerator or denominator, it doesn't make a difference.
