Graph the inequality, x - y ≥ -1 treating it like a general equation.

Similarly graph the inequality x ≤ 0.

Now, shade the region of the given inequalities

according to their signs.

The green line represents x – y ≥ -1.

The red line represents x ≤ 0.

The common shaded region is the solution of the given system.

The shaded region continues till the end of the straight lines.

Graph the inequality, x + y ≤ 4 treating it like a general equation.

Similarly graph the inequalities x ≥ 2 and y ≥ 0.

Now, shade the region of the given inequalities

according to their signs.

The red line represents x + y ≤ 4.

The green line represents x ≥ 2.

The blue line represents y ≥ 0.

The common shaded region is the solution of the given system.

The shaded region continues till the end of the straight lines.
