Answer:
Undefined
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the two points:
(y2 - y1) / (x2 - x1)
(1 + 7) / (-7 + 7)
8/0
= undefined
So, the slope is undefined, since you cannot divide by zero.
The slope of the lines that passes through the points (-7,-7) and (-7.1) is an infinite slope.
The slope formula is described as follows:
Therefore,
x₁ = -7
x₂ = -7
y₁ = -7
y₂ = 1
m = 1 - (-7) / -7 - (-7)
m = 1 + 7 / -7 + 7
m = 8 / 0
m = infinity
The slope is an infinite slope. Therefore, it is a vertical line.
