I believe if Socratic is right the answer is -x+4y=8
Answer:
with proportional relationships, you can simply divide the y coordinate by the x coordinate to find the unit rate: In this case, if (5,4) lies on the line then you have 5 lbs of potatoes for 4 dollars or .80 cents for 1lb of potatoes. The point (10,8) represents 10 lbs of potatoes for 8 dollars. Here you can see that dividing 8 by 10 we once again get the unit rate of .80 cents per 1 lb of potatoes.
x = lbs of potatoes and y = price(4,3)....this means 4 lbs of potatoes cost $ 33/4 = 0.75 cents per lb <== 1 lb of potatoes cost 0.75(8,6)...this means that 8 lbs of potatoes cost $ 6
Hope this helps

Matrix A was expressed in the form of a 2x2
i'm not sure if this helps or not but here you go
<span>denominator is </span>number below the line in a common fraction.
Here's picture to show what is a denominator:
Given-
Cost of milk 4 years ago = £1.05
To find-
Percentage increase in cost
Solution-
Increase in cost = £ ( 1.26 - 1.05 )
→ £ 0.21
Percentage increase :-


Therefore, Percentage increase of the cost of milk over 4 years is <u>2</u><u>0</u><u>%</u> .
