Math Problem Statement
Solution
The problem asks to identify which ordered pair lies on the same line as the points shown in the graph.
Step-by-step solution:
-
Determine the equation of the line: Observing the graph, we see that the line passes through these points:
- (the origin)
Using these points, calculate the slope :
Since the line passes through the origin, its equation is:
-
Check which ordered pair satisfies : Evaluate each option:
- : , not on the line.
- : , on the line.
- : , not on the line.
- : , on the line.
-
Correct options: Both and lie on the line.
