Gap-fill

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

The midpoint of $(\var{xa1},\var{ya1})$ and $(\var{xa2},\var{ya2})$ is $\large($ Gap 0., Gap 1. $\large)$ .

Advice

{line_and_2points()}

The midpoint of two points is simply the point whose $x$ coordinate is the average of the other $x$ coordinates, and whose $y$ coordinate is the average of the other $y$ coordinates. That is, the midpoint of $(\var{xa1},\var{ya1})$ and $(\var{xa2},\var{ya2})$ is the point $\left(\simplify[basic]{({xa1}+{xa2})/2},\simplify[basic]{({ya1}+{ya2})/2}\right)=\left(\simplify{({xa1}+{xa2})/2},\simplify{({ya1}+{ya2})/2}\right)=\left(\simplify{{(xa1+xa2)/2}},\simplify{{(ya1+ya2)/2}}\right)$.
