ugh! its been a while since ive done this.im not 100% sure but i think it would be3y=1x+3simplify ty=1/3x+1hmmmmmmm.......

I'm pretty sure it would be 3x-y=-2.

NO WAIT! I multiplied wrong... Derr... I think it's 3x-y=0, but that's a really weird answer...

Linear equations are of the form y = mx + bSince we already know m = 3, we would havey = 3x + bThen, we have the point (1, 3), which means that x will be 1, when y is 3. If we substitute on the equation we would have3 = 3*1 + b3 = 3 + bb = 0Going back to the equation we would have y = 3x or 3x - y = 0

3x - y = 0 is right.  If you put it in point - slope form with your given information:y = 3x + bYou can plug the point into the equation and solve for b, which winds up being 0.  Then you move 3x and y to the same time, and voila: 3x - y = 0
