-- Find any point where y=4
-- Find another point where y=4
-- With your ruler, draw a line between the two points. You have a horizontal line, and every point on it has y=4 no matter what 'x' is.
The equation for every straight line is [ y = mx+b ].
This is the line where (m = 0) and (b = 4).
A horizontal line that intersects the graph at (0,4)
To graph the equation y = 4 , plot points where the y-coordinate is 4 for various x-values and connect these points to form a horizontal line. This line extends indefinitely and indicates that the value of y stays constant at 4, regardless of x. The line's slope is 0, confirming its horizontal nature.
