Where would (0.5,2) be potted ? Please answer this !!
NISA [10]

 (0.5,2)

2 is y value

         l

         l

---------------

        l

        l

x value is on dashed line (0.5)

y value is on more separated line going up and down. (2)

To plot 0.5, you can put it as an equation. 0.5= 1/2. So to plot it, 0.5 is half of 1. So plot it as in between the 1 and 0.

To plot 2 go up to the two on the y axis and then go over 0.5 and plot a point.

That is you're plotted point for (0.5,2)


Hope it helps!
