what is the equation of this line in slope intercept,standard,and point slope form. (-3,-2) and (1,6)

Which equation is in which form mat?

what is the equation of this line in slope intercept,standard,and point slope form. (-3,-2) and (1,6)?

ans: 

let x₁=-3,  x₂=1,   y₁=-2,    y₂=6

formula is m = 

m=6+2/1+3

m=8/4

m=2

Point Slope Form:

y+2=2(x+3)

y+2=2x+6

2x-y+4=0

answer may be:2x-y+4=0
