    Can you show me how to graph x-6y greater than or equal to -18

    FIRST, change it into Slope-Intercept form ~ \[x - 6y \ge -18 \]Subtract x from both sides. \[-6y \ge -x - 18\]Divide both sides by -6. Flip the sign to <=. \[y \le \frac{ 1 }{ 6 } x + 3\]------------------------ Remember: y = mx + b m is slope b is y-intercept \[y \le \frac{ 1 }{ 6 } x + 3\]Slope is 1/6 y-intercept is 3 Graph the equation. Step 1) Plot the y-intercept (3) at point (0, 3). Step 2) Remember that:\[slope = \frac{ rise }{ run } = \frac{ 1 }{ 6 }\]So from point (0, 3) RISE 1 space up, and RUN 6 spaces to the right. Plot this point.

    The sign was LESS than or EQUAL to. So the line would be SOLID. The shading would be underneath the line, or on the side that includes the origin.
