Question

How do you graph `x+y=6` by plotting points?

Answer 1

See below.

Explanation:

Subtract `x` from both sides to get:

`y = 6 - x`

Put in values for `x` and calculate corresponding values of `y`.
Example:
`x = 1` gives `y = 5`
`x = 10` gives `y = -4`
Since it is the equation of a straight line you only need to find to points, then draw a straight lint between them.
