Answer:
Hope this helps!
Explanation:
Slope = 5/-2
Slope (m) = 
ΔY
ΔX
= 
5
-2
= -2.5
θ = 
arctan( ΔY ) + 180°
ΔX
= 111.80140948635°
ΔX = -1 – 3 = -4
ΔY = 5 – -5 = 10
Distance (d) = √ΔX2 + ΔY2 = √116 = 10.770329614269
Equation of the line:
y = -2.5x + 2.5
or
y = 
- 5 x
2
 + 5
2
When x=0, y = 2.5
When y=0, x = 1
