Answer:

D. 3x +y = 23

Step-by-step explanation:

If you know what "standard form" is, then you recognize that only one offered answer choice is actually in standard form. That is the correct choice.

3x + y = 23

_____

Standard form for a linear equation is ...

ax +by = c

where a, b, c are mutually prime integers and a ≥ 0. If a = 0, then b > 0. (The leading coefficient is positive.)

determine weather y varies directly with x. if so, find the constant variation and write the equation

REY [17]

Answer:

Yes, k = 1/3 and y = 1/3x

Step-by-step explanation:

$\text{The given line passes through the origin, hence it has equation of the form:}\\y=kx$

$\text{Therefore y varies directly as x.}The line passes through the point (3,1)}$

$\text{This implies that,}$

$1=k(3)\\k=\frac{1}{3}$ $\text{Hence the constant of variation is}$ ⇒ $\frac{1}{3}$

The equation would be ⇒ $y=\frac{1}{3} x$
