@hero or @darkknight

IamAku:

jesus-

IamAku:

uh

IamAku:

xio

XioGonz:

Yeah?

IamAku:

ill try-

\(\color{#0cbb34}{\text{Originally Posted by}}\) @IamAku ill try- \(\color{#0cbb34}{\text{End of Quote}}\) Lol okayy

IamAku:

wait-

IamAku:

how'd u get ur first answer-

XioGonz:

I clicked on it accidentally and I can't unclick it >.>

IamAku:

oh

dude:

Hmm not quite The center point in the equation will be the opposite of the sign in the graph itself (x-1)^2+(y-2)^2 will give you point (1,2) Then, the right side is the radius squared (:

IamAku:

thx dude

IamAku:

my brain is kinda-

IamAku:

yh-

XioGonz:

dude:

What's the center point in the graph?

XioGonz:

(-1,-2)

Timmyspu:

ok and what are the other 4 points that make it a circle

dude:

Yeah For the x and y in the parenthesis you want it to have the opposite sign \((x\color{red}{+}1)^2+(y\color{red}{+}2)^2\) -> (-1,-2) For the right side of the equation You had =7 The radius is 7 but the equation is \(r^2\) So, just square 7

Timmyspu:

so what would be your awnser

XioGonz:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @dude Yeah For the x and y in the parenthesis you want it to have the opposite sign \((x\color{red}{+}1)^2+(y\color{red}{+}2)^2\) -> (-1,-2) For the right side of the equation You had =7 The radius is 7 but the equation is \(r^2\) So, just square 7 \(\color{#0cbb34}{\text{End of Quote}}\) Ohhhhhhhhhhh okay I get it now, Thank you!
