When the inequality sign is </> (less than/greater than), the dot is an open circle.
When the inequality sign is ≤/≥ (less than or equal to/greater than or equal to), the dot is a closed circle.
y = number that is a solution/makes the inequality true
y ≤ 8 (y is any number less than or equal to 8)
#1: y = 0 is part of the solution set.
Yes because if you substitute/plug in 0 into "y" in the inequality, since y = 0:
0 ≤ 8 0 is less than 8.
#2: y = 8 is part of the solution set.
Yes because if you plug it into the inequality:
8 ≤ 8 8 is equal to 8
#3: y = 10 is part of the solution set.
No because if you plug it into the inequality:
10 ≤ 8 10 is not less than or equal to 8
#4: There is an open circle on the graph at 8.
No because the inequality sign is ≤, so there should be a closed circle on 8.
#5: There is a closed circle on the graph at 8.
Yes because the inequality sign is ≤
#6: The arrow on the graph points left.
Yes because if the arrow is pointing left then the numbers are decreasing, and y is any number less than or equal to 8.
#7: The arrow on the graph points right.
No because if the arrow is point right then the numbers are increasing, but y is not a number greater than 8.
Your answer is the 1st, 2nd, 5th, and 6th option
