The equation of a circle centered at (h, k) and with radius r is
In this case, the center is point (2, 1), so h = 2, and k = 1.
We also need the radius. We are not given the radius, but we have the center and a point on the circle. The distance between the center and any point on the circle is the radius. We can use the distance formula to find the distance between points (2, 1) and (5, 2).
The radius is the distance between the points, so
Now we have all the information we need, so we can write the equation of the circle.
Answer:
I am assuming that the whole 3x - 6 in the fraction is the numerator
the this simplifies to 3x (3x - 6)
= 9x^2 - 18x (C)
Answer:
I believe its y=
My thinking:
I think when the slope intercepts the Y line is when it’s called the y-intercepts and that’s basically how got my answer.
Please do correct me if I’m wrong
It’s been a while since I done something like that ( it hasn’t been that long actually, I just forgot a lot of it)
Sorry if I’m wrong, I hope that I at least helped a Little
