Question

Find the equation of the line belowA. y=3xB. y=6xC. y=1/3xD. y=1/6x

Answer 1

To find the correct option we can replace the point (3,1) that belongs to the line and has to satisfy the equation:

`\begin{gathered} \text{The point is (x,y)=(3,1) we use the value of x=3 in each option and check the value of y:} \\ A\text{. y=3x }\Rightarrow x=3;y=9\text{ }\\e1 \\ B\text{. y=6x }\Rightarrow x=3;y=18\\e1 \\ C\text{. y=1/3x }\Rightarrow x=3;y=1(Correct!!) \\ D\text{. y=1/6x }\Rightarrow x=3;y=(1)/(2)\\e1 \end{gathered}`

So, the correct option is C.
