Asked by Samantha

How would you graph an equation with an exponent?

The equation I have says x^2 + y^2 = 9

How is that graphed?

Do you mean on a calculator? type it in just as you have above, except put paranthesis around it.
Answered by Cinnamon
x2+y2=9 square root --> x+y= +-3--> y= -x +- 3 type into calculator it should be a straight line

Cinnamon, that is so wrong.
Samanth, the equation is a circle at the origin with radius 3. You need to memorize this equation

(x-h)^2 + (y-j)^2=r^2

a circle at (h,j) with radius r.
