Question

How do you graph `y= -4` by plotting points?

Answer 1

`"see explanation"`

Explanation:

`y=-4" is a special equation of a line"`

`"in that it is horizontal , parallel to the x-axis and passing"`
`"through all points in the plane with a y-coordinate of - 4"`

`"choosing any coordinate points with a y-coordinate of - 4"`
`"and drawing a straight line through them gives graph"`
graph{y-0.001x+4=0 [-10, 10, -5, 5]}
