Respuesta :

In an equation like that, y would double into 2y. But just keep in mind that what happens to one side must happen to another.

The result shows that if the value of x is doubled, the value of y will be quadrupled

Given the equation y = -2x,

if x doubles, we will replace x with 2x as shown;

y = 2 (2x)

y = 4x

y is equal to 4 times the variable x

From the result, we can see that if the value of x is doubled, the value of y will be quadrupled
