∙ 13y agoFirst, get in standard form.
3X - Y = 21
-Y = -3X + 21
Y = 3X - 21
now set both variables equal to 0 to find intercepts/values
3X - 21 = 0
3X = 21
X = 7
----------
Y = 3(0) - 21
Y = - 21

What is the coefficient of x in 3xy?
-3xy is a monomial where x and y are variables and -3 is the coefficient of the monomial.If we know the value of y, we have to substitute it for y, and we say that -3(y-value) is the coefficient of x.
