Which two points lie on a line with an undefined slope?

a. (-2,0) and (-2,5)
b. (-2,0) and (0,-2)
c. (0,0) and (2,2)
d. (3,0) and (2,0)

Option A.   and

Step-by-step explanation:

we know that

A vertical line has an undefined slope

The lines parallel to the y-axis are vertical lines

The points that lie on a vertical line has the same x-coordinate

In this problem

the points and has the same x-coordinate

therefore

The points lie on a line with  an undefined slope (vertical line)

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

3=log(n)=2

answer a: product property
