Answer:

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#.
