Question

Li believes that the graph shows a direct variation. On a coordinate plane, a line goes through points (0, 1) and (2, 0). Why is Li incorrect in saying that the graph shows a direct variation? The graph does not have a constant rate of change. When the x-value is 0, the y-value is 1. The slope is negative. The relationship is proportional.

Answer 1

Answer

B) When the x-value is 0, and the y-value is 1

Step-by-step explanation:

Answer 2

When the x-value is 0, the y-value is 1.

Which graph shows a direct variation?

A relationship between two variables, x, and y, symbolizes a proportional variation if it can be described in the form y/x = k or y = kx.

In a proportional relationship, the constant of proportionality k exists equivalent to the slope m of the line and the line passes through the origin.

Recognize that in a direct variation

For x=0, the value of y exists equivalent to zero.

Therefore, the graph exists not have a direct variation, because

When the x-value exists at 0, the y-value exists at 1.
