Hey there!

If everything is on the same horizontal level, it is at the same elevation, or height. On a graph, the elevation is the y-value. So, if we want the points to on the same horizontal line, they have to have the same y-value.

The points that all share the y-value of -1 are (7,-1), (2,-1), and (-3,-1). Since (-3,9) is at a different y-value it is not on the horizontal line of y=-1.

Have a wonderful day!

Answer:

A (7,-1)

B (2,-1)

D (-3,-1)

Step-by-step explanation:

Well lets plot the following points on a graph first,

A (7,-1)

B (2,-1)

C (-3,9)

D (-3,-1)

Look at the image below ↓

By looking at the graph we can tell that points,

A, B, and D lie on the same horizontal line.

Thus,

points A, B, and D lie on the same horizontal line.

Hope this helps :)
