• 2

• -2

• 7

• -5

• 8

It is the number/s multiplied with the variables OR the numbers in front of the variable.

Sometimes in the process of solving equations, multiplying or squaring expressions involving a variable will lead to a numerical result that does not make the original equation true.

• intercepts

• intersection
