Answer
The equation of line x = 2.
Step by step explanation
First we have to find the slope from the given two points.
(2, 1) and (2, -2)
Here x1 =2, y1 = 1, x2 =2 and y2 = -2
Slope formula =
![(y2 - y1)/(x2 - x1)](https://img.qammunity.org/2019/formulas/mathematics/high-school/7tm65cgb5qjgom2sdnxyvrv7rdnlxjikul.png)
= (-2 - 1) /(2 - 2)
= -3/0
Slope(m) = 0
Here the value of x coordinates are the same and slope = 0, therefore, it is vertical line.
Hence the equation x = 2.
Thank you.
