    I'm assuming that the equation of the line is actually y=-2x+6. The intersection of two lines is where both equations are satisfied so we can use both equations to solve for x and y. So by plugging in "-2x+6" everywhere we see y we have:

    ((-2x+6+3)^2)+((x-2)^2)=10

    4x^2-36x+81+x^2-4x+4=10

    5x^2-40x+75=0

    x^2-8x+15=0

    (x-5)(x-3)=0

    So x=5 and x=3 work.

    Plugging those into y=-2x+6 we get y=-2(5)+6=-4 and y=-2(3)+6=0

    So the solutions (5,-4) and (3,0) which are all the points of intersection.
