Question

Given that y varies directly with x, and y = 6 when x = -5, find y when x = -8.

A) 9.6
B) 6.7
C) 3.75
D) -9.6

Answer 1

When x = -8, the value of y is 9.6.

Step-by-step explanation:

To find the value of y when x = -8, we need to use the fact that y varies directly with x. This means that the ratio between y and x is always the same. We can use the given information to set up a proportion:

(y)/(x) = (6)/(-5)

Now we can solve for y:

(y)/(-8) = (6)/(-5)

y = (6)/(-5) * (-8)

y = 9.6

So the value of y when x = -8 is 9.6.
