Answer:
The quantities used by Manuela were correct
Step-by-step explanation:
The question is
Did Manuela use the right quantities?
Let
x -----> the parts of oil
y ----> the parts of vinegar
we know that
The ratio of the parts of oil by the parts of vinegar of recipe is
Determine the relation used by Manuela
Compare with the recipe
Is true, the quantities are proportional
therefore
The quantities used by Manuela were correct
A. 5
B. -3/1
C. Negative
D. You have to go down 3 over to the right one from where your y-intercept is.
To plot the y intercept plot (0,5)
To plot the next point go down 3 over 1 to the right from the y-ing
The answer to this would be C because you can multiply everything by 3 and still have a consistent-dependent system.
