I handed back that quiz from Friday, and I made some suggestions for improvement in a number of areas. Here are a few.
- 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
- use parentheses around the point’s coordinates, like
- use equals signs as you simplify the coordinates, like
- 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
