A coordinate plane, with the x-axis from $-10$10 to $10$10 and the y-axis also from $-10$10 to $10$10. Two lines are drawn on the plane: a $solid$solid horizontal line which crosses the y-axis at $\left(0,-3\right)$(0,3), and a $solid$solid line which crosses the x-axis at $\left(-\frac{5}{4},0\right)$(54,0) and the y-axis at $\left(0,-5\right)$(0,5). These lines intersect, dividing the coordinate plane into four regions. The $\text{upper left}$upper left region is shaded.

$y$y$\ge$$-4x-5$4x5 or $y$y$\ge$$-3$3
