<span>Y = -4x - 18
</span>This is the order pair (-5,2)
The equation to represent the relationship of the weights shown on the scale s 
The weights are given as:


The total weight on one side, where there are 4 small squares and 3 large squares is:



The total weight on the other side, where there are 2 small squares, 2 large squares and 1 triangle is:





The weight of the triangle is x.
So, we have:

The weights on both sides are equal, because the scale is balanced.
So, we have:

Hence, the equation is
