Attached is a series of errors made by Drew, an enthusiastic, but busy algebra student who did his practice test quickly and made some classic errors. In your group, talk about the many errors Drew made. Where did he go wrong in his thinking? Don't give correct answers to one another, but individually do Drew's problems and submit the your work and the correct answers to the drop box.

The following exercises were given to the class. Drew quickly finished the work on the exercises and submitted them to the drop box. The problem is that his answers are wrong. Where did Drew go wrong? AND what is the correct answer for each?

• Factor

Drew’s answer:

2. Simplify

Here’s what Drew did. = =

Drew’s answer:

• Graph 2y = 3x + 4

Drew’s graph goes through 4 on the y-axis, since 4 is in the place of b in the slope-intercept form, y = mx + b. He also used 3/1 as the slope, since 3 is in the place of m. So from 4 on the y-axis, he went up three and to the right 1 to put another point. Then he drew his line through (0,4) and (7,1).
