Question

FInd the equation of a circle with
Center: (-15,9)
Tangent to x=-17

Answer 1

\[(x+15)^{2}+(y-9)^{2}=r ^{2}\]
we get radius by moving from -15 to -17 ie r=2
\[(x+15)^{2}+(y-9)^{2}=2^{2}\]

Answer 2

that works

Answer 3

a sketch can really help

Answer 4

Wow, thank you so much :)
My algebra II teacher gave us a huge packet on equations of circles but all of them with different types of problems to "study" for the final, but he never taugh us any of this :/

Answer 5

The drawing helps ! I see it now!

Answer 6

cool :)
