Question

In a direct variation, y=
–
60 when x=5. Write a direct variation equation that shows the relationship between x and y.

Answer 1

The direct variation equation can be written as y = kx, where k is the constant of variation.

To find k, we can use the given information:

y = -60, x = 5

Substituting these values into the equation, we have:

-60 = 5k

Solving for k, we have:

k = -60/5 = -12

Therefore, the direct variation equation that shows the relationship between x and y is:

y = -12x
