Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.
Given that x varies directly with y, if we introduce a constant of proportionality, k, the expression becomes
x = ky
If x = - 4 when y = 6, then
- 4 = 6k
k = - 4/6 = - 2/3
Therefore, the equation that relates x and y is
x = -2y/3
