Question

How do you graph `y = -2` by plotting points?

Answer 1

Make a T chart with the values of x and y, the line will be a horizontal line with a height of `-2`

Explanation:

Generally, graphs show a function, for example, `y=x-3`. In that case, one would draw a graph by substituting an `x` value into the equation and connecting the points.

In this case, however, there are no `x` values in the equation. Therefore, regardless of the number on the `x`-axis, the `y` value will remain the same (`-2`). Therefore, the line will be a horizontal line with a slope of zero and a `y`-intercept of `-2`.
