through: (3,-1), perp. to y = -x + 1
5

Answer:
The answer is y = -5/3+4
Step-by-step explanation:
alright so first we find the reciprocal of 3/5 because it is perpendicular
which is -5/3
we then create an equation and solve for b (y-int) by substituting our coordinates (3, -1)
Sub x and y and isolate b
y = -5/3x + b
-1 = -5/3(3) + b
-1 = -15/3 + b
-1 = -5 + b
+5 +5
4 = b
equation
y = -5/3x + 4
