1. In each graph, the two lines are parallel to each other.
2. Each set of equations have the same slope.
3. Equations that have the same slope as each other will always be parallel to each other.
Multiply all the terms by the same value to eliminate fraction denominators
a/9=-4
9 . a/9=9(-4)
The dot means multiplication
Then simplify to simplify cancel the multiplied terms that are in the denominator
a=9 . -4
Multiply the number
9 . -4 =36
And don’t forget to add the negative sign so the answer is
a= -36
