what does 7x + 9y >=693 look like on a graph

First let's transform the inequality 7x+ 9y≥693

by subtracting both sides by 7x we have :

9y≥-7x+693

Dividing both sides by 9 it comes y≥-7x⁄9+693

let's consider the linear function y=-7x/9+693.

it is a downward line (y-intercept 693).

Therefore, the solution of the inequality 7x+ 9y≥693 is the area of the plane above the line defined by y=-7x/9+693.
