Find intersections between equations

Hello! I'd like to know how to find the intersection between 2 equations, symbolically or with solve(). for example, the intersections between a line and a circle: y=-3x+1 , x^2+y^2=16 Thank you!

For symbolic answer

syms x
y = -3*x + 1;
eq = x^2+y^2==16;

sol = vpasolve(eq)
sol =
  3/10 - 159^(1/2)/10
  159^(1/2)/10 + 3/10

convert it to double

double(sol)
ans =
   -0.9610
    1.5610
