This is just a line there are infinitely many solutions or points...for every value of x there is a value for y which is three times x. Pick any x solve for y and that is one of the infinite number of ordered pairs produced by the equation.
y=3x (0,0),(1,3),(2,6),(3,9).....................
Answer:
Step-by-step explanation:
what 3x9
To calculate this, we have to divide 2 1/2 by 8.
first, i wil turn 2 1/2 into fraction:
it's

and if we divide this by 8, we multiply the denominator by 8:

and this is the answer!
F(x). "f(x) = ... " is the classic way of writing a function. And there are other ways, as you will see! .... Example: {(2, 4), (2,5), (7,3)} is not a function because {2,4} and {2,5} means that 2 could be related to .
