Answer:

Skills needed: Linear Equations, Algebra
Explanation:
1) We are trying to find the slope of a line given two coordinate pairs.
They are:
and
Think of these two coordinate pairs as:
and

The formula for slope would be:
or
(the second one says change in y over change in x)
2) So let's assign values:
is

is

is

is

Slope would be:

Therefore
