how do you graph x=4
would plotting the point (4,0) work?
Yes because if you graph x=4, your line should be vertical and by graphing (4,0), you would get the same answer.
The point (4,0) is one point on the x=4 line. To plot the line just draw a line parallel to the y axis that passes through (4,0). [x=4 passes through (4,0), (4,1), (4,2), (4,3), 4,4), (4,-1), (4,-2), (4,-3) etc.
To graph the equation x = 4, you can plot a single point on the graph. The equation x = 4 represents a vertical line passing through the x-coordinate 4.
So, to graph x = 4, you can simply plot a point at (4, 0), where the x-coordinate is 4 and the y-coordinate is 0.
Since this is a vertical line, all points on this line will have an x-coordinate of 4, but the y-coordinate can be any value. The point (4, 0) is a commonly chosen point since it lies on the x-axis. However, you can plot any other point on this line, such as (4, 3) or (4, -2), as long as the x-coordinate remains 4.
So, yes, plotting the point (4, 0) is a valid way to graph the equation x = 4.
