y = mx + b is the equation of a line in slope intercept form. m is the slope. b is the y intercept.
Find the slope, m = (y2 - y1)/(x2-x1)
(2,-1) is point 1, and (2,5) is point 2. (x,y)
(5 - -1) / (2-2) = 6/0 = undefined slope. This is a vertical line.
x = 2

Graph the two points, You'll see that they form a vertical line x = 2. Division by 0 is a no-no!

yes, he is correct. The slope of the line through the points (2,-1) and (2,5) is (5--1)/(2-2)=6/0 , which is undefined. By graphing the two lines, you will see that they both lie on the vertical line x = 2. The slope is undefined

Why does x=2 ,wouldn’t it just equal 611/22/23
