Question

which function rule is represented by the tablex 0 1 2 3 y 3 5 7 9a y=x+3b y=x+6c y=2x+3d y=4x+1

Answer 1

Taking any two coordinate from the table (0,3) and (1,5) and using two point form,

$\begin{gathered} \frac{y-3}{x-0}=\frac{5-3}{1-0} \\ y-3=2x \\ y=2x+3 \end{gathered}$

Thus, option (c) is the correct solution.
