sorry but i don't know  good luck on your question

first draw a graph of $y = 4 - 5x$.
now your inequality states that $y\ge\4-5x$, so we know that at each x-value, y must be greater than or equal to this value.
this indicates that the line $y = 4 - 5x$ should be INCLUDED as on that line y is equal to $4-5x$. we can also say that all points above the line should be INCLUDED as the inequality is y is equal to or greater than this value.
so, in summary, you need to draw the straight line graph of $y=4-5x$ (making sure that the line itself is SOLID) and then shade the area above it.
here is a picture of this:
