Answer:
y=-1/2x+7/2
Step-by-step explanation:
two lines are perpendicular if the product of the slopes is equal to -1
the slope for y=2x+4 is 2
2*x=-1
x=-1/2
the formula for the slope is
(y2-y1)/(x2-x1)=m
we know y1 and x1
(y+5)/(x+3)=-1/2
y+5=x+3/2
2y+10=x+3
2y=x-7
y=-1/2x+7/2
Answer: The 80ml is the best deal
Step-by-step explanation:
Bc the half price of 45 is 22.5 so 45 + 22.5 equals $67.50 and the 80ml would equal 55.
