find the equation of the line passing through (-3,5) with an undefined slope

Hi Melissa;

I would just like to add one piece of information to what Michael and Nataliya said.

Slope is defined as the change of y divided by the change of x...

(change of y)/(change of x)

or

(y-y

_{1})/(x-x_{1})A denominator, also known as divisor, can never be zero in any equation. If it is, the equation is characterized as undefined. You requested an equation with an undefined slope, a slope whose value of x does not change. Henceforth, the answer you received was...

x=-3

Only one figure can be inputted into the denominator. That figure is -3. Henceforth, the equation of (x-x

_{1}) is non-workable, and undefined.There is no change of x-value. Change of x-value is zero.
