Question

How do you graph `x=-2`?

Answer 1

see explanation.

Explanation:

The equation of a line in the form `color(blue)"x=c "`is a vertical line, parallel to the y-axis and passing through all points in the plane with an x-coordinate of c.

Select 2/3 points with an x-coordinate x = -2 and draw a straight line through them.

`"That is " (-2,-1),(-2,0),(-2,2)" and " (-2,4)`
