I’d recommend writing the equation as y=…. so rearrange it first

They implicitly told you the gradient when they told you it was perpendicular to that line and so the gradient must be the negative reciprocal of that second line

You now know the coefficient of x once you’ve rearranged it, and you can set it as that value

Next you’d sub in the values of x and y on that point since you’re told it goes through there

That would find you the value of c

I haven’t actually done the question but if you get stuck at any point lmk and I can
