Question

Help find the equation of the circle with center (-3,1) and the circle is tangent to the line x=4

Answer 1

Would it be (x+3)^2 + (y-1)^2=7^2 ?

Answer 2

the center is good, lets check for radius to confirm tho

Answer 3

the line x=4 is how far away from the line x=-3? 7 units right?

so radius = 7

looks fine to me

Answer 4

Thank you

Answer 5
