Worth 20 points try to answer as many as possible tell me which one you are answering and tell me how you got the answer and your work 1) y varies inversely with x. if y= 40 when x= 16, find x when y= -5. 2) y varies directly with x. if y= 15 when x= -18, find y when x=1.6. 3) if x and y vary directly, as x decreases, what happens to the value of x? 4) if x and y vary directly, as y increases, what happens to the value of x?

1) x = (40/-5)*16 = -128
.. Since the variation is inverse, (old y)/(new y) = (new x)/(old x). Note the new/old ratios are upside down. Thus (new x) = (old x)*(old y)/(new y), as above.

2) y = (1.6/18)*-15 = -1 1/3
.. Since the variation is direct, (new y)/(old y) = (new x)/(old x)

3) x DECREASES
.. When variation is direct, both variables move in the same direction. Here, the problem statement tells you what happens to x! (Perhaps a typo?)

4) x INCREASES
.. See 3).

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
