Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

$\simplify{y={c[0]}x+{c[1]}}$

$x=$ Unnamed gap

Advice

Simply rearrange the equations for the required variable.

No fraction can be divided by $0$ , so we make sure our answers can't produce that result.

When you have given your answer, look at your denominator.

The value(s) that make the denominator $0$ are the value(s) you define as not included in the range.

Remember for squared variables, there are two possible answers; the positive and negative.

Give a worked solution to the whole question.
