Answer:
Option 2) When the x-value is 0, the y-value is 1.
Step-by-step explanation:
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <em>and the line passes through the origin </em>
Remember that in a direct variation
For x=0, the value of y is equal to zero too
therefore
The graph is not a direct variation , because
When the x-value is 0, the y-value is 1.
