From 50 K to boiling temperature, T increases linearly as $Q = m c Δ T .$ Hence $T - t$ graph will be a straight line inclined to time axis.

During boiling, $Q = m L$

Temperature remains constant till boiling is complete and graph will be a straight line parallel to time axis.

After that, temperature increases linearly. $T - t$ graph will be a straight line inclined to time axis.
