Question

What is the slope of the line that passes through (3,7) and (-1,1)

Answer 1

move the points so that one of them is at the origin

(3,7) and (-1,1)
1 -1 1 -1
-------------
4 6 0 0

then the slope is defined by the none zero point as: y/x

Answer 2

Answer 3

Point is well taken :)

Answer 4

Both points XD

Answer 5

Since line passes through (3,7) and (-1,1)
therefore
\[x_{1}=3 \]
\[x_{2}=-1\]
\[y_{1}=7\]
\[y_{2}=1\]
Slope of line is given as
\[slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{1-7}{-1-3}=\frac{-6}{-4}=\frac{3}{2}\]
