The match would be:
A. D
A. D
Response A: This is not the correct graph as it shows a line with positive slope, whereas the inequality has a negative coefficient for y.
Response B: This is also not the correct graph as it shows a line with negative slope, but the inequality has a negative coefficient for y.
Response C: This is the correct graph as it shows a line with negative slope, representing the inequality -2y > 2.
Response D: This is not the correct graph as it shows a vertical line, whereas the inequality does not have any restrictions on x.
−2y > 2
To solve an inequality involving the variable y, we need to isolate y on one side of the inequality sign. Let's start by dividing both sides of the inequality by −2. Since we are dividing by a negative number, the inequality sign should flip.
When we divide −2y by −2, we get y on the left side of the inequality. On the right side, we have 2 divided by −2, which is −1.
y < −1
Now, we have the solution to the inequality, which states that y is less than −1. Let's graph this inequality on a number line to match it with the corresponding graph.
On a number line, we mark a point at −1 and shade the region to the left of it since the inequality states that y is less than −1. This shaded region represents all the possible values of y that satisfy the inequality.
Now, let's look at the given options:
A. The graph of inequality −2y > 2 does not match y < −1 since it shows the region to the right of −1.
B. The graph of inequality −2y > 2 does not match y < −1 since it shows the region to the right of −1.
C. The graph of inequality −2y > 2 matches y < −1 since it correctly shows the shaded region to the left of −1.
D. The graph of inequality −2y > 2 does not match y < −1 since it shows the region to the right of −1.
So, the correct match for the inequality −2y > 2 is option C.
Response: C
