Question

What is the slope of the line that contains the point -6,-7 and -6,2

Answer 1

We know that coordinates are labeled (x,y)
The formula to find slope is (Y2-Y1)/(X2-X1)
So (2- (-7))/(-6-(-6) undefined because the denominator is zero. The line looks like a vertical line at x=-6

Answer 2

Slope is undefined.

Explanation:

slope is defined as the steepness of a line.It is also called gradient.

It is denoted by m.

It is ratio of change in y to change in x.

m=Δy/Δx=
`y_(2) -y_(1) /x_(2) -x_(1)`

From question statement, we observe that

`x_(1) =-6,y_(1) =-7`

`x_(2) =-6,y_(2) =2`

putting above values in formula to find slope,we get

m=2-(-7)/-6-(-6)

m=2+7/-6+6

m=5/0= undefined.

The slope of vertical line is undefined.
