Analyzing a circle, y^2 x^2 = 9, and a linear function g(x) with ordered pairs (-2,-1; 1,1; 4,3). will they intersect?

The equation in your problem y^2 x^2=9 is a circle with the center (0,0) and the radius of 3. 

The 2nd ordered pair 1,1 is in this circle because 1^2+1&2=2. Therefore, point 1/1 is inside the circle and any  line containing that point is in the circle. 

Yes, 1,1 intersects.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
