Linear Equation- Equation of a line passing through points

Question

What is the slope-intercept form of the equation of the line passing through the points (-1,-4) with an undefined slope?

Answer 1

slope is defined as rise/run or $(y_2-y_1)/(x_2-x_1)$,in your case $x_1=-1$ and $y_1=-4$,which means that $x_2=-1$ and $y_2$ is equal to something else, this actual means that line is straight line,in your case it is just $x=-1$.look please
