Answer: Mason has 150 buttons.
Step-by-step explanation: Brandon has 25 buttons. If Mason has 6 times as many, all you have to do is multiply 25 times 6. You end up with 150 buttons.
Morse code is essentially the same as binary. That is, there are two "digits", a dot or a dash.
There are 26 letters in the English alphabet. Clearly, we can't just use one dot or dash, since that could only encode 2 letters at the most. We can't use two symbols because that could only encode 4 letters at the most. Similarly, 3 symbols means

letters at most.
We have to select the smallest power of 2 that exceeds or is equal to 26. In this case,

, so we would have to use up to 5 symbols to encode each letter in the alphabet.
Y=mx+b
plug in the point
3=-1*-4+b
3=4+b
b=-1
y=-1x-1
