If y varies directly with x, and y = 10 when x = 4, write the direct linear variation equation
2 answers:
The answer is c. I chose the answer c because y=5/2x(I think you forgot to put the x in the question) filled in with the numbers are true while a, b, and d aren't true if filled with 10 and 4.
Answer:
Step-by-step explanation:
Given,
y varies directly with x,
I.e.
Where,
k = constant of proportionality,
We have,
y = 10 when x = 4
From equation (1),
Again from equation (1),
Which is the required direct linear variation equation.
