Question

Billy is analyzing a circle, y2 + x2 = 81, and a linear function g(x). Will they intersect?


y2 + x2 = 81

g(x)

graph of the function y squared plus x squared equals 81
x g(x)
−1 −8.5
0 −9
1 −9.5
Yes, at positive x coordinates
Yes, at negative y coordinates
Yes, at negative and positive x coordinates
No, they will not intersect @Directrix @Callisto

Answer 2

I guess we have to get the equation of the line and then see if it intersects the circle.

Answer 3

ok

Answer 4

yes at

Answer 5

You can use the online calculator to generate the equation of the line through two given points.

The calculator is at this link:

@Callisto My explanation does not resonate with Asker. Asker did not participate so I'll leave the discussion with you. :)

Answer 11

I just tryr to get help and no matter who i tag no one answers my questions and it just really stresses me out i really am sorry

Answer 12

If you don't have a graphing calculation, here is what you can do:
Step 1. Find the equation of g(x).
As given in the question, g(x) is a linear function. Since you are given at least two points, you can use the two point form: \(\frac{y-y_1}{x-x_1} = \frac{y_2-y_1}{x_2-x_1}\) to find equation.
Maybe you can pick two points from the given three points first?
