If the coordinates of the intersection point of the image of the linear function y = 3x + 7 and the X axis are the solutions of the quadratic equation 2Y KX = 18, then K=
The coordinate of the intersection point of the image and the X axis of the linear function y = 3x + 7 is (- 7 / 3,0)
The coordinate is the solution of the quadratic equation 2Y KX = 18
That is, 2 * 0-k * (- 7 / 3) = 18
That is, k = 54 / 7
