Question

The x and y values shown in the table have a proportional relationship.Drag a number for x and a number for y into the table that have the same proportional relationship.

Answer 1

Given that x and y satisfy a proportional relationship, then the next equation relates the variables:

y = kx

where k (a constant) can be obtained with a pair of values (x,y). In this case:

$k=\frac{y}{x}=\frac{2}{-1}=-2$

Now, we need to select two values from the list that satisfy this value of k.

$k=\frac{-6}{3}=-2$

that is, y = -6 and x = 3

x | y

-1 | 2

3 | -6
