Question

Find the slope of the line represented by the table of values.

Answer 1

Slope = (9-3)/(5-2) = 6/3 = 2

answer
A) 2 

Answer 2

The slope is 2. Here's why:

Take any two pairs on the table (in this case, I took 6,11 and 2, 3). Plug the two pairs in with the point-slope equation, or:

y2 - y1/x2 - x1

Which would look like this:

3 - 11/2 - 6

Now, follow the order of operations to solve:

3 - 11 = -8
2 - 6 = -4
-8/-4 = 2

And the result of dividing -8 by -4 is 2, which is our slope :)
