Undefined slope is the same as no slope. The x value is the same for the entire line. highlight%28x=4%29.

An UNDEFINED slope means that the DENOMINATOR in the slope equation: matrix%281%2C3%2C+m%2C+%22=%22%2C+%28y%5B1%5D+-+y%5B2%5D%29%2F%28x%5B1%5D+-+x%5B2%5D%29%29 equals 0.

Therefore, we set the denominator equal to 0, and get: 4 - x = 0

- x = - 4

highlight_green%28x+=+%28-+4%29%2F%28-+1%29+=+4%29
