∫A( 1,4),S△AOB=2/ 15
∴AC=4∴OB= 1/ 15
∴ point b coordinates (-115,0)
Let the analytical formula of straight line AB be y = KX+B.
Next, use the undetermined coefficient method to find the resolution function. You should know, so I won't teach. There are other situations that you can think for yourself. (Hint: Draw the Y-axis image of AB) The steps and thinking methods are similar to this!
If you are satisfied, adopt it. Thank you!
