O_O it's raining link
:O
but can you help me?
you didnt understand?
first of all u can observe that the slope is negetive right?
ya I guess so
to find the graph, all you have to do is plug in values to x and find the corresponding ordinate to the plane
so the graph will look like this|dw:1414768003644:dw|
now u have to determine the co-orninates
the graph looks like answer D
o wait no C actually
say for x=10 y = -0.4x y = -0.4(10) y = -4 when x=0 y =-0.4(0) y = 0 plotting you'll have: |dw:1414768063995:dw|
So C?
...
yes thats the concept but none of the options look right
ok well thanks to you both.... who should I give the medal to?
