Question

How do you graph `y+3=0` by plotting points?

Answer 1

Choose arbitrarily any two x values, say, x =`-5`and x = 10. Join `(-5, -3` and #(10, -3) and extend the line on both sides.,

Explanation:

y + 3 = 0 or y =`-3`, for any x, is the line parallel to the x-axis, at a depth 3 units, from the x-axis.
