Write a direct variation equation, y = kx, that satisfies the ordered pairs in the table.
-$\begin{array} { c | c | c | c }
\mathrm { x } & 0 & - 4 & - 14 \
\hline \mathrm { y } & 0 & 2 & 7
\end{array}$
A) $y = - \frac { 1 } { 2 } x$
B) $y = \frac { 2 } { 7 } x$
C)y = -2x
D) $y = \frac { 7 } { 2 } x$

Question

Write a direct variation equation, y = kx, that satisfies the ordered pairs in the table.
-$\begin{array} { c | c | c | c } 
\mathrm { x } & 0 & - 4 & - 14 \
\hline \mathrm { y } & 0 & 2 & 7
\end{array}$
A) $y = - \frac { 1 } { 2 } x$
B) $y = \frac { 2 } { 7 } x$
C)y = -2x
D) $y = \frac { 7 } { 2 } x$

Quizplus · Accepted Answer

The correct answer is A because y = - (1/2)x satisfies the ordered pairs in the table.
