Answer:
slope is undefined
Step-by-step explanation:
Using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
If x₂ - x₁ = 0
Since division by zero is undefined then the slope of the line is undefined
This applies to a vertical line parallel to the y- axis
First, determine what 15% of $40 is.
Convert 15% to a decimal: 0.15
Then multiply this decimal by $40: 0.15 x 40 = 6
So the discount is $6.
We subtract the discount from original price to get sale price.
40-6= 34
So the item will cost $34.
Answer:
A circle whose center is located at point (a, b) having a radius of length r has the equation:
(x -a)² + (y -b)² = r²
(x - -3)^2 + (y -5)^2 = 2^2 =
x^2 +6x + 9 + y^2 -10y +25 =4
