x = 3
Step-by-step explanation:
Maybe you want the equation of the line.
__
A vertical line has undefined slope. Its equation is of the form ...
x = constant
In order for the line to go through a point with an x-coordinate of 3, the constant must be 3.
x = 3 . . . . equation of the line
x=71
-46+x=25
add 46 to both sides (you do the inverse!)
x=71
I need the picture but maybe you can take a guess i think i will be 7.7777777777777777777777777777 but im not sure
