The correct option is y = 3x - 6, (which is option 2).
The slope of the line is calculated by using the formula;
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{0-\lbrack-6\rbrack}{2-0} \\ m=\frac{0+6}{2} \\ m=3 \end{gathered}[/tex]Given that the slope is 3 (from our calcuation), the line which is written in slope intercept form is
[tex]\begin{gathered} y=mx+b \\ y=3x-6 \\ (\text{Note that b is the y-intercept, the point wh}ere\text{ x equals 0, then y equals -6)} \end{gathered}[/tex]
