(3, -7) and (-1, 1)
To find slope of a line using 2 points
we use formula
[tex]\frac{y_2 - y_2}{x_2-x_1}[/tex]
(3, -7) is (x1,y1) and (-1, 1) is (x2,y2)
Here x1= 3 and y1= -7
x2=-1 and y2=1
[tex]\frac{1- (-7)}{-1-3}[/tex]
[tex]\frac{8}{-4}[/tex]=-2
slope of a line using 2 points (3, -7) and (-1, 1) is -2
