Question 786133: I'm helping my child with a quiz that waa brought home - "Linear equations" Lesson 1.2 quiz
1. Create an expression that is equal to the expression 2x-9. I'm lost on what we are to do. Is this supposed to be hypothetical?
Then in question 2 we are asked to graph the two expressions to verify they are equal - so referencing question one should there be 2 answers to question 1?

Definition of Equivalent Expression
"Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same."
For question one you can create an equivalent expression by extracting a common factor, for example 2(x-9/2) = 2x -9.
I would draw graphs for each equation and mark several equivalent points to show they are equal.
