What step did she do wrong
or did she get it right?

Priya got it right.

Step-by-step explanation:

I wouldn't have done it the way she did, but it's still correct. You can check with a calculator (if Khan Academy allows you to) or do it like this:

If f = 4, then f ÷ 0.25 should be 16.

4 ÷ 0.25 = 16

So, Priya got it right.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
