Answer:
a) (2, 8)
Step-by-step explanation:
The easiest way is to insert the coordinates into the inequality.
a) (2, 8)

b) (0, 1)

c) (3, 7)

d) (5, 8)

You could also plot the inequality and test the points. You would get a graph like the one below. Point (2, 8) is the only one that satisfies the inequality. Points (0, 1) and (3, 7) do not satisfy the inequality because they are on a dashed line.
Trying to get 3:1
Divide 236 by four=59
Then times 59 by 3
The ratio now is 177:59
3:1
Answer:
The correct option is Option A: Yes, that is the correct step
Step-by-step explanation:
Wane was asked to solve the inequality 
He decides that he needs to multiply both sides by 3.
We need to tell if the step is correct?
So, solving the inequality

We need to multiply both sides by 3, to get value of x i.e.

So, Wanes step is correct.
The correct option is Option A: Yes, that is the correct step
