Question

Find the constant of variation for the relationship shown in the following table:
(x)1,2,3,4
(Y)3,6,9,12
(A)2
(b)4
(C)3
(D)1

Answer 1

So, what doees 1*_=3
2*x=6

Answer 2

hint: constant of variation = rate of change = slope
\(\bf \begin{array}{lllllll}
x&1&{\color{red}{ 2}}&3&{\color{red}{ 4}}\\
y&3&{\color{blue}{ 6}}&9&{\color{blue}{ 12}}
\end{array}\qquad slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\)

Answer 3

In x and y there is a same repeating as the rule althugh it is you can use the formula
