Use the Pythagorean theorem for this. (a^2+b^2=c^2)
a=9, b=12, c=x
9^2+12^2=c^2
81 + 144 = c^2
225 = c^2
c =15
the answer is c
No the points have to be on a cross on the x and y axis
The equation of a line is y-mx+b with m being slope and b being y-intercept. Using the values provided in your problem, your answer would be y=2/3x+9, or C.
