Question

If the value of "y" varies directly with "X"

and y = -51 when x = 3, find "y" if x = 2.
Enter the number

Answer 1

x : 3 :: y : -1

9 : 3 :: y : -1

3y = -9

y = -3

Answer 2

-34

Explanation:

Y varies directly as x then the equation relating them is

y= kx ⬅️k is the constant of variation

To find k use the condition y= -51 when x=3

k= -17

y= -17x⬅️equation of variation

when x=2, then

y= -17*2=-34
