The relationship between the cost of books and pens is an illustration of linear equation.
The linear equation is (a)
From the question, we have:
x exceeds 2 times y by 10
Rewrite as:
x exceeds 2y by 10
Exceed means plus (+)
So, we have:
Equate the above equation to 0
Hence, the required equation is (a)

Hi!
Given:
Multiply both sides by
<em>Notice the sign was flipped. This is because when you multiply or divide by a negative number, you must always flip the sign!</em>
<u>Now, for the graph:</u>

For < or > signs, it should be an open circle. For or
signs, it should be closed.
Since is less than 6, it should go to the left. Since it's a < symbol, it should be open. Therefore your answer is B.
(looks like you were right!!)
