So the -4x is the M and then 6 is the B. So m is the slope and B is the y-intercept. The 6 goes on the y axis and the -4 will be how the line looks. It’ll be rise (-4) over run (1).
The largest angle is opposite to the longest side. In this case, DF is the longest, so the angle facing DF, ∠E, is the largest. The largest angle ∠E is opposite the side DF.
