1.5 / 5 = .3, not sure why it says to round to nearest tenth though
Answer:
(4,6)
Step-by-step explanation:
The midpoint=(
=(4,6)
y = 1/3x
The slope is 1/3 ( the slope is the number with the variable x).
There is no other operation ( addition or subtraction) so the y- intercept is 0
The first point of the graph would be (0,0)
Calculate another point , lets use x = 3
y = 1/3(3) = 1
The second point is (3,1)
The line of the graph is an angled line which is located in quadrant 1 and 3.

The expression x=20-3D will present the amount Amy has left after buying D sodas.
Step-by-step explanation:
Given,
Total amount = 20 quarters
Cost of sodas = $0.75 = 0.75*100 = 75 cents
25 cents = 1 quarter
1 cent = 
75 cents =
= 3 quarters
Amount of D sodas = 3D
Let x be the amount left with Amy.
Amount left = total amount - Amount of D sodas

The expression x=20-3D will present the amount Amy has left after buying D sodas.
