In order to graph the two systems of equalities you need to solve for y
x+y<= -5
y<=x-5
4x-5y>-15
-5y>-4x-15
y<4/5x+3*
*notice that the sign changes because you are dividing by a negative number
Now you will be able to graph the two lines acting as though the signs <=, and < are equals signs however when it comes to drawing the lines to connect the dots, you need to make sure that the <= graph has a doted line and the < has a solid line.
You then graph the two lines shading them based on their inequality

@SamuelAlden917 thats olryt
dont forget to consider y inequality
when its y< then region below is shaded
when its y> region above is shaded
