The slope is normally represented by m so it is 0.
It is not documented why the letter m was chosen for slope. However, mathematician John Conway suggested that m could mean 'modulus of slope'.
slope can be represented by any variables, such that, the variable representing the slope is defined. by convention, mathematicians and mathematics books authors used and are using "m" as the variable for slope. (recommended to have further historical research on this matter)
y - 3x = 8 standard form is y = mx + b m = slope y = 3x + 8 in this form slope m is 3 The perpendicular line slope is the negative inverse of m -1/m = -1/3
M=1000 anything larger requires a combination of numerals
M is simply just a random number picked by math maticians. Almost the whole alphabet stands for something.
It is the letter M.
It is the letter M.
It is the letter M.
Your statement is correct. y=mx+b when m is the slope and b is the y-intercept.
