Answer: LAST OPTION.
Step-by-step explanation:
You need to remember that a line intercepts the x-axis when y is equal to zero ([tex]y=0[/tex])
Knowing this and given the graph of the line [tex]2x -3y = 12[/tex], you can observe in the figure attached that this line intercepts the x-axis at this point:
[tex](6,0)[/tex]
Where:
[tex]x=6[/tex] and [tex]y=0[/tex]
Therefore, you can identify that the x-intercept is the x-coordinate of this point, which is:
[tex]x=6[/tex]
This matches with the last option.
