Question

The y-term has a coefficient of -3, and the x-term has a coefficient of 1. The expression does not have a constant term. Which expression could she have written?

Answer 1

" -3 y + x"

Explanation:

There seems to be a term in the variable "y" and another one in the variable "x". The coefficient of the term in y is "-3" which means that the term in the variable "y" should read: = -3y".

The coefficient of the term in x is "1", which means that this term should read: "1 x", or simply "x".

There is no "constant" term, which means that there is no term with just a numerical value (and no letters).

Therefore, the most likely expression the person could have written is: " -3 y + x"
