exif: {"Image DocumentName": "This the general from of a vertical straight line.", "Image ImageDescription": "Example 5: A(a,0) and B(0,-a), find the locus of P(x,y) such that the gradient AP is twice the gradient of BP. Hint: Try to sketch a rough diagram of the information. P(x,y) A(a,0) B(-a,0) Evaluate LHS and RHS. Hint: There we must use the gradient formula fro 2 points: m AP. m BP. Rearrange, by cross multiplying. Expand, simplify and rearrange. Divide by y.
