Graph x-y=10

And don't just write a number, I need to know what points to plot on a graph lol

If you have a graphing calculator you can put the graph y=x-10 into y and then it second table, and it should give you the coordinates. But here are some (-2,-12),(-1,-11)0,-10),(1,-9)(2,-8)

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
