Does the line pass through the origin?
Graph:
Is the Relationship Proportional? Yes.
Explanation: The line passing through the given points passes through the origin.
Before we begin, let's take a look at the information given in the table of values.
Cucumbers, x | 2 | 3 | 4 |
---|---|---|---|
Tomatoes, y | 4 | 6 | 8 |
First, let's plot the given points.
The graph of a proportional relation is a single, straight line in the coordinate plane that passes through the origin. Let's check if we can pass a single line through these points and the origin.
Since the line passes through the origin, so x and y are proportional.
