Can someone help clarify this please, for equation of a line passing through (-2,3) slope 2/3, i get up to the point where 3 + 4/3 = b, but don't get how this equals 13/3... can someone explain that part to me?
also, similarly on an equation of a line passing through (3,-1) and is perpendicular to 4y=3x+5, I get lost and come up with something like y=-4/3x and cant figure the rest out... any help is highly appreciated, thanks.
