Rearrange the linear equation: x ? 3 y + 10 = 0

1. Prove that the line x ? 3 y + 10 = 0 is a tangent to the circle with equation x 2 + y 2 = 10 and find the coordinates of the point of contact. Rearrange the linear equation: x ? 3 y + 10 = 0. x = 3 y ? 10. Substitute this linear equation into the quadratic equation:.
