In the rectangular coordinate system, if the line x = 3y + 5 passes through points (m,n) and (m + 2,n + p), what is the value of p?	Pick:
A) -2	B) 0	C) 1/2	D) 1	E) 2/3
x = 3y+5, and thus y = x/3 - 5/3   The slope is 1/3.   The slope of a line through points (m,n) and (m + 2,n + p) is (n+p-n)/(m+2-m) = p/2   p/2 = 1/3 and thus p = 2/3   The answer is 2/3.
