Consider m = y2 - y1/ x2 - x1 . which x1 and x2-values would determine that the line is vertical? justify your answer

Step-by-step explanation:

We were given the slope formula;

This line is vertical if the denominator is zero.

That is when

This implies that;

Justification;

When , then, the line passes through;

 and

The slope now become

The equation of the line is

This implies that;

... This is the equation of a vertical line.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
