To find the slope of the line containing (1,-3) and (3,-5) use this formula slope (m)= y2-y1 / x2-x1
(1,-3) is (x1, y1) and (3,-5) is (x2, y2) plug these values into your formula
m= -5 -(-3) / 3 - 1
m= -2 / 2
m= -1
So your slope of the line is -1
I hope this helps!!

slope is change-in-y / change-in-x:
m = (y2 - y1) / (x2 - x1)
m = (-5 - (-3)) / (3 - 1)
m = -2 / 2
m = -1
I get -1 for the slope. I think the previous respondent missed the minus-sign on "-5".

(5--3)/3-1 = 8/2 = slope of 4
(y+3)/(x-1)=4
y+3=4x-4
y=4x-7

m = (y2 - y1)/(x2 - x1)
m = (-5 - (-3)) / (3 - 1)
m = -2/2
m = -1
