The answer is B. That is not a valid way to sample as it is not randomly selected.
Answer:
x=2
y=3
Step-by-step explanation:
Answer:
y*(x+2)=k
so y= k/(x+2)
Step-by-step explanation:
Answer:y=-3x+4

Answer:
7x +5y = -5
Step-by-step explanation:
You can find the perpendicular line by swapping the x- and y-coefficients, and negating one of them. The new constant can be found by using the given point.
7x +5y = 7(-5) +5(6) = -5
The perpendicular line through (-5, 6) is ...
7x +5y = -5
