You can put this solution on YOUR website! If we need to draw a line oin a graph and shade in the correct area, how would we find where to draw the line for y is less than or equal to 2x -5?
--------------
y <= 2x - 5
Treat it like an equation and find 2 points.
y = 2x - 5
Pick any values for x and find y
x = 0, y = -5 --> (0,-5)
x = 3, y = 1 --> (3,1)
----
Plot the 2 points, draw a line thru them.
The line is y = 2x - 5
The area below the line is
y < 2x - 5
---
y <= 2x - 5 is the area below, and including the line.
