Do questions 4 and 7 on page 162, Ex. 7.6.

On question 7 you may have difficulty understanding what they mean when they say "foot of the perpendicular". The foot of the perpendicular is the point where the perpendicular lines intersect. So, if you look at the diagram below as an example, then Q is the foot of the perpendicular from K to MN.

Do questions 7, 8 and 11 on page 158 from Ex. 7.5.

Remember, we have learned about lines that intersect and lines that are parallel. Some questions are just written in a confusing manner, but the solutions are actually really simple. Break things up into steps to understand the problems. If you still have trouble then post your questions on the blog.

Do questions 9 and 10 on page 155, Ex 7.4.

Again, draw a diagram where you feel you don't understand what the question is asking. There are cases where it is impossible to visualize something and that is okay. Look at your notes as well!

Finish question 6 on page 155 (Ex 7.4) and then do the following:

#1 and 2

Page 146, Ex. 7.1

#1 and 4

Remember, you should draw graphs whenever you need to visualize something in these questions. In fact, I think it will be very difficult to do these questions without drawing a diagram. Below is a diagram to help you with question 6 that we started in class today. I know some of you were confused about how the question was worded and what they meant with the line through A and B meeting at the axes at P and Q. Basically, P and Q are the names given to the x and y "intercepts" and I have marked them on the sketch below. Now, you know how to find all the information asked for in the question, just look at what we've done with linear functions so far.
