The only type of line with undefined slope is a vertical line.
In a vertical line, all points have the same x-coordinate.
The general equation of a vertical line is x = k, where k is the x-coordinate of all points on the line. If you are given one point, then you know the x-coordinate of that point, but since all points have the same x-coordinate, you also know the x-coordinate of all points.
Equation is: x = -6

Same explanation as above.
x = 2
Density is Mass ÷ Volume so...
A. Mass and Volume
Answer:
The value of k is 4.
Step-by-step explanation:
To find the missing coordinate, we can use the slope equation and plug in all known values.
m(slope) = (y2 - y1)/(x2 - x1)
-1 = (k - 0)/(-2 - 2)
-1 = k/-4
Now we can solve using cross multiplication.
-1 = k/-4
k*1 = -1*-4
k = 4
