Answer:
To plot the given inequality.
[tex]y\leq-3x+6[/tex]
To plot the inequality, first plot and graph the line y=-3x+6 (slope is -3, y intercept is 6)
To find the region which satisfies the inequality, take a point above or below and substitute in the equation, the point is in the region will satisfies the inequality.
The required graph is,
