Find the Midpoint Between Two Points
The question is worded as follows:

find the midpoint (a,b) between the two points (-5,5),(-4,2).

Then it has two answer fields. one for A= and another for B=. How am I supposed to answer this?

Hi Champloo11,
The question is for you to calculate the values of x-coordinate 'a' and the y -coordinate 'b' of the mid-point.
Is the question clear to you now.

The midpoint betweens two others is defined as the one with equal distance to both. That would mean that if $X=(-5,5)$, $Y=(-4,2)$ and $M$ is the midpoint between those, we have:

$d(X,M) = d(Y,M)$

Since this is $\mathbb{R}^2$, the midpoint would be middleway the line connecting $X$ and $Y$.

Thank you everyone, I kept misreading the question. I thought it was asking for 2 individual points, and not the assignment of the points x and y as a and b.
