Question

how do i graph linear equations with only one number and variable

Answer 1

All you have to do is assign values to the variable, for exaple, given the following equation:

y(x) = 2x

For x=1

y(1) = 2(1) = 2

For x=4

y(4) = 2(4) = 8

For x=0

y(0)= 2(0) = 0

For x=-10

y(-10)= 2(-10) = -20

and so on...
