Question

Which statement best explains if the graph correctly represents the proportional relationship y = −2x?

Answer 1

d. It does, the points shown on the line would be part of y = −2x.
is the answer let me know if this helped

Answer 2

Answer:

So, it does, the points shown on the line would be part of y = −2x.

Step-by-step explanation:

1)The linear function $y=-2x$ is a decreasing one therefore it is graphed from 2nd Quadrant to 4th Quadrant. In addition to this, since is linear parameter b is equal to zero, the line crosses its origin. Finally, its slope is equal to -2.

2)We have (-1,2) and (2,4),  pointed out. Linear functions with b=0 are proportional ones. Proportional functions have its slope calculated by:

$k=\frac{y}{x}=\frac{2}{-1}=\frac{4}{-2}\Rightarrow k=-2$

So, it does, the points shown on the line would be part of y = −2x.
