Write the equation of the line that passes through (4,8)and (4,6) write the equation in slope intercept form

x = 4

Step-by-step explanation:

If you were to plot the given points, you would quickly see that this is a vertical line where x = 4 (a visual is always a good place to start).  

Vertical lines have a slope that is undefined and are written in the form of x = .

If you had plugged into the slope formula , where () is (4, 8) and () is (4,6) the result would be as follows:

    =

    =

Because you can not divide by 0, the slope is in fact undefined.
