This paper considers the problem of testing the intercepts of two simple linear models following a pre-test on the suspected equality of slopes. The unrestricted test (UT), restricted test (RT) and pre-test test (PTT) are proposed from the M-tests using the M-estimation methodology. The asymptotic power functions of the UT, RT and PTT are given. The computational comparisons of power function of the three tests are provided. The PTT achieves a reasonable dominance over the other two tests asymptotically.
