Look at the axis labels of your graph. There is NO mention of Vce there! The vertical axis is Ic, the collector current. The horizontal axis is Vc, the voltage at the collector (relative to ground). It is NOT Vce. As I pointed out before, you are GIVEN Vc in the problem statement. Is it 53V. All you have to do is find the collector current that corresponds to a collector voltage of 53V.Ok, so first I calculated Vb using the formula (R2/R1+R2)75V. I then used the formula Vbe=Vb-Ve to get Ve=23.9V-.7V . Finally I used the formula Vce=Vc-Ve to get Vce=53v-23.9V. The only problem is that the voltage Vce and Ic Dont line up correctly on the load line so I think i am sitll doing it wrong.
