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.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
