It is called the slope of the line
C is the correct answer. A line is proportional if it is a straight line that passes through the origin, and while it does pass through the origin, it isn’t completely straight.
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (- 2, - 5 )
m =
=
= 
Since division by zero is undefined then the slope is undefined

Area of a circle = PI x r^2
Area = 3.14 x 11^2
Area = 3.14 x 121
Area = 379.94 square cm.
