What is -16 less than or equal to y - 9 ?

-16 what, X?. I need more detail than just numbers.

Graph the line y = x . (Upward rising line with slope 1 passing through the origin.) 

Then shade the half-plane above that line. All of the points in that half-plane, including the line y = x , satisfy the equation y ≥ x . [ Which is the same as x ≤ y ]i think this is right dk

The answer is a good luck
