The equation is 12x-32=p. p is the perimeter. You would have to work backward and add 32 to p, making the equation now 12x=p+32. Now you have to divide it by 12, so the final expression is x=p+32/12 ( x equals p plus 32 over 12)
Point slope formula:

We know that:
y1=-1
x1=2
m=-5
So we plug those into the formula

negative + negative= positive so..
