I handed back that quiz from Friday, and I made some suggestions for improvement in a number of areas. Here are a few.

## Graphing

- label your x- and y-axes, including arrows on the ends
- include a scale, to the left of the y-axis and below the x-axis

## Finding Midpoint

- use parentheses around the point’s coordinates, like
- use equals signs as you simplify the coordinates, like

## Finding Length

- extend the root sign over the entire expression, like
- be careful matching brackets, and use square brackets if necessary:
- don’t lose your negative sign too early: , not yet

## Finding the Perpendicular Bisector

- label your slopes and equations clearly, using
*words*if necessary - when finding a negative reciprocal,
*change*the sign (don’t just move it to the denominator!) - lots of people found the slope, but didn’t find the equation.

## The Triangle Question

- explain how to solve the problem in steps
- measuring is not the same as calculating
