Question

If y = - 4 when x = 2 and y varies directly with x then find y whenx= -6.​

Answer 1

Answer:

Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.

Answer 2

Answer:

y=4

Step-by-step explanation:

x+y= -2

-6+y= -2

y= 4
