Answer:
These two lines are graphs of non-proportional relationships because
" They do not go through the origin " ⇒ B
Explanation:
If two quantities x and y are proportional, then
- The relationship between them is represented by the equation y = k x
- k is the constant of proportionality
- The relationship represents graphically by a line must pass through the origin point
From the given graph
∵ The first line intersects the y-axis at point (0, 3)
∴ The line does not pass through the origin
∴ The line is a graph of the non-proportional relationship
∵ The second line intersects the y-axis at point (0, -2)
∴ The line does not pass through the origin
∴ The line is a graph of the non-proportional relationship
These two lines are graphs of non-proportional relationships because
" They do not go through the origin "
