Complete the square and you'll find it's a circle. You could choose any four points on the circle.

$2x^2+16x-3y^2-12y=-8$ $2(x^2+8x)-3(y^2+4y)=-8$ $2(x^2+8x+16)-3(y^2+4y+4)=-8+32-12=12$ $2(x+4)^2-3(y+2)^2=12$ $\frac{(x+4)^2}{6}-\frac{(y+2)^2}{4}=1$

;first step was divide by two to make the calculation easier second was to factor and group third was to complete the square and add and subtract on the right what was added and subtracted on the left. last step was to divide by 12

this is as you said a hyperbola, not a circle.

now pick a y and solve for x, or pick an x and solve for y
