Question

How do you graph all the points that satisfy `y>= 2x-5`?

Answer 1

Area above Line y = 2x - 5

Explanation:

y >- 2x - 5
Firs, graph the Line y = 2x - 5 by its 2 intercept.
Make x = 0 --> y = -5
Make y = 0 --> x = 5/2.
The solution set of the inequality is the area above the Line.
Check with the origin.
Replace x = 0 and y = 0 into the inequality, we get 0> -5.
It is true, then O is inside the solution set.
Note. The Line is included in the solution set.
