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

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