Question

The black line is the graph of y= x. Which of theseequations could represent the blue line?yty = 0.001xy = 2xy = -xy = 1/2x

Answer 1

`y=(1)/(2)x`

lets discard the other options:

- for y=2x: the slope of this line is greater than the slope of the black line, so it would be more steep, but the blue line is not, so this is not the answer.

-for y=-x: by seeing the picture we see that the slope of the blue line has the same sign of the black one, so it discard this option.
