Answer:
45x happy to help ya :)
Step-by-step explanation:
Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.
Hmmm A millimeter would be too big for that .
I think millionths of a meter would be about right. Micrometers.
2.000 pluse 4.00=600.000
4 pluse 2=6
thousand pluse hundreds=hundre thousandths
