How do you write the standard form of a line given (-2,-6) and slope: undefined?

x = -2

An undefined indicates that we have a vertical line parallel to the y-axis and passing through all points in the plane with an x-coordinate = constant ( c) The equation is written in the form x = c.

In this case the line passes through (-2 ,-6) and therefore the constant is the value of the x-coordinate. That is - 2.

Hence the equation of the line is x = - 2 graph{y-1000x-2000=0 [-10, 10, -5, 5]}
