Answer:
C) y = 3x
Step-by-step explanation:
The given graph show a proportional relationship that it's modelled by a linear equation. We can make all the process to calculate the equation that belongs to that behaviour. We just have to find the slope:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}} \\m=\frac{18}{6}=3[/tex]
Using the slope interception formula: [tex]y=mx+b[/tex]
[tex]y=3x+0[/tex]
Because the interception with the vertical axis is null, so the equation would be:
[tex]y=3x[/tex]
Therefore the answer is C.
