Find the image of the triangle ABC with the vertices A(2,1),B(4,3),C(3,1) under a stretch, scale factor 2. with invariant line y=x
hi Karuna,
Welcome to the forum.
In a stretch the movement is perpendicular to the invarient line. For a scale factor of 2, points move away to twice the distance.
Hope that helps.

Thanks for the feedback. Answer is correct. i would like to understand how to prove this with mathematical steps or equation? also can you tell me which software you are using to plot the graph?
