Question

The difference in the x-coordinates of two points is 3, and the difference in the y-coordinates of the two points is 6. What is the slope of the line that passes through the points?

a.2
b.3
c.6
d.9

Answer 1

1, 12

4, 18

To find the slope between these two points (which fits the criteria) we can use a simple equation.

18 - 12 / 4 - 1

6 / 3

2

The answer is a, or 2.
