What is the slope of the line that passes through the points left bracket, minus, 4, comma, 4, right bracket(−4,4) and left bracket, minus, 1, comma, 3, right bracket(−1,3)? Write your answer in simplest form.

you need to learn how to type math. So, let's start over, and show the question as it should have been typed:

What is the slope of the line that passes through the points (-4,4) and (-1,3)?
the slope is (3-4)/(-1+4) = -1/3

The slope of the line that passes through the points (-4,4) and (-1,3) is -1/3.
