The slope of a line passing through two points is the ratio between the difference of the y coordinates and the difference of the x coordinates. In formulas, you have
If you plug your values, you have
which is undefined.
In fact, since the two points share the same x coordinate, the segment AB is vertical, and the slope is not defined for vertical lines.
Answer:
2+x=5
x+1=4
(-5)+x=-2
are equivalent
(x=3)
Step-by-step explanation:
A decimal number for sure
