Q

x = -2.3423591 would be a straight vertical slope or a straight horizontal slope, and would it be a undefined or zero slope

A

Since it starts on the x axis, it cross vertically, which means it is an undefined slope.

Q

S is the initial salary, D is the amount of dumplings you make and M is the amount of money you receive, what is the x and y, and why is that? How would you write this in an equation?

A

D is x since M is always dependent, therefore M=DX+S
