R^2=(x-6)^2+(y-4)^2
r^2=(6-2)^2+(4-1)^2, r^2=16+9=25
(x-6)^2+(y-4)^2=25
the answer is 16.5cm
just add 15 +1.5 and you get 16.5
The answer is -3x^2+10xy+8y^2
First of all, lets get y on its own side of the equation.

This is slope intercept form, y=mx+b, where m is slope.
we can see that m=2, so the slope is 2 or 
Answer: I am not that sure but I think it’s first third and fifth
