y235x = 4137 adding 235x to both sides we get?:

just do the pattern in the formula point slope form y  y1 = m(x  x1). y =235x4137 do some factoring here

y  y1 = m(x  x1). y  0 = 235(x  x1). find x1 using 235 and 4137 using division or factoring

to find x1 235 x1=4137, what is x1?

I'm not sure if this is really necessary, but if you split the 4137 into 2 numbers, you can find a nice multiple of 235, so it will make your division a little bit easier. \[\large y=235x4137\]\[\large y=235x3995142\]\[\large y+142=235x3995\]Then do what mark is suggesting, factor out the 235 from each term on the right :D \[\large y+142=235(x17)\] Just an idea! :) Looks like you're on the right track already though ^^ so don't mind me.

yes plug them in to the formula y  y1 = m(x  x1). y  0 = 235(x  x1).

4137 / 235 = 17.60425532 on this one we will have an excess of 0.60425532

You don't have to split up the numbers if you don't want ^^ it makes it look nicer, but i don't suppose it's entirely necessary. Just leave your x1 term as a fraction like this. \[\large y0=235(xx1)\]\[\large y0=235(x\frac{4137}{235})\] If splitting up the 4137 into a number divisible by 235 is confusing you, then just do it this way :D
