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.
