Question

If y varies directly as x and x=2 when y=−4, find y when x=−6.

Equation: ____________

Solution: y = ___________

Answer 1

Equation: x × -2 = y

Solution: y = 12

Explanation:

if (x = 2) is (y = -4) then (x = 1) is (y = -2) so if (x = -6) is (y = 12) if we follow the equation [x × -2 = y] which was found using the first set of variables and dividing each by 2.
