Discussion:

Slope of a non-vertical line through (x1, y1), (x2, y2) is

(y2 - y1)/(x2-x1)

Substituting our values into this formula gives

( 5 - 1 )  / ( -1 - ( -3) )  =

4/ ( -1 + 3) =

4 /2 =

Thank you,

Slope is 2.

Step-by-step explanation:

Slope= 2

Step by Step Explanation:  

Since, given points are:  

(x1,y1) = (-3,1)

(x2,y2) = (-1,5)

Now, by using formula of slope.  

Slope= y2-y1 / x2-x1

Slope= 5-1 / -1-(-3)

Slope= 4 / 2  

Slope= 2  

Therefore required slope is 2.
