Find the point(s) of intersection between the circle

Question

x^2 + y^2 = 50 and the linear equation y = 2x − 5.

Answer 1

You could graph the circle and the line and SEE the point(s) of intersection. Or since the line is already re-arranged for y, sub that into the cirle equation and solve for x. And then solve for y : )
