Answer:
yes it is.
Step-by-step explanation:
Answer:
A. y + 5 = negative two-fifths (x + 3)
Answer:
y = -1/2x + 1/2
Step-by-step explanation:
perpendicular lines have slopes that are opposite signs and reciprocal
therefore, use m=-1/2 and point (9, -4) to complete the equation by finding 'b' (the y-intercept)
-4 = -1/2(9) + b
-4 = -9/2 + b
-4 + 9/2 = b
-4 + 4
= b
b = 
64.50-.10=64.40
64.40-47=17.4
(my way of working math when i'm not in school is weird, but still accurate)
17.4/4=4.35.
It's average change per day is -4.35.
