Find out how the parabola y = 2x passes through the origin after translation, and the vertex is on the line y = - x [cannot be the origin]

Because the image passes through the origin, so C = 0, so the new parabola becomes y = 2x & # 178; + BX. That is to say, the vertex of the image is on y = - x, so according to the vertex formula (- B / 2a, - B & # 178; / 4a), - B & # 178; / 8 = B / 4, we get
