Slope intercept form   is    y = mx + b     m = slope   b = y intercept (value when x = 0)

y = -1/2 x + b     now put in the point given to calculate 'b'

-4 = -1/2(-3) + b      so b = -5 1/2

y = -1/2x  - 5 1/2

 

Point slope form :

y − y1 = m(x − x1)       sub in the point given

y - -4  = -1/2(x - -3)

y+4 = -1/2(x+3)
