Answer by mangopeeler07(462) (Show Source): You can put this solution on YOUR website!
y=f(x)
f(x)=7x

First plug in a number for x. Maybe 1 first:
f(1)=7

So one point is (1,7).

Now plug in 2:
f(2)=14

So another point is (2,14).

Now plug in 3:
f(3)=21

So another point is (3,21).

Keeping plugging in numbers this way and plot them on a graph. Remember to plug in negative numbers too, such as:

f(-1)=-7
(-1,-7)

I hope this helps!
