Question 313520: find the equation of line through the point (-1,5) with undefined slope
Answer by texttutoring(324)   (Show Source):
You can put this solution on YOUR website! If it has an undefined slope, it means it is a straight vertical line. This is because the equation for slope is m=rise/run. Undefined means that you divided by zero, or that the run is zero. The line has no change in x.
It passes through -1,5 which means that the equation of the vertical line must be x=-1
