we are learning to graph linear equations and he gave us these notes but I don't know where he got the ordered pairs.

see below

Step-by-step explanation:

x- 3y ≤ 6

We pick points and see if they are true for the inequality

(0,0)

See if it is true

0-3(0)  ≤ 6

0+0 ≤ 6

0 ≤ 6

True

Picking another point

(6,-1)

6-3(-1) ≤ 6

6+3 ≤ 6

9 ≤ 6

This is false so this point is not a solution

We can see this is true in the attached graph

seems like d

step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
