Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(4, 3)
m =
= 
Division by zero is undefined thus the slope of CD is undefined
Answer:
D.$315
Step-by-step explanation:
$450=100%
100%-20%-10%=70%
$450×70%=$450×70/100
=$315
