Look all you have to do is place them like this: 1) y-y1=m(x-x1)which would be
y+4 =-2(x+4)when you have a subtracting sing and a negative together it changes to positive or else it would of been y- -4.
2)y-5=0(x- -5) or (x+5)
3)4-2/-1+4=2/3=m.also as y+1=2/3(x-4)
4)-3+3/5+2=0/7=m=no solution meaning that I don't think that you have to do the slope intercept.Im running out of time so I can't do more of the problems.
