Hi Emily,
For question #5 of review #3, to find the “unit” price, you are trying to find out how much it would cost for 1 pen. So you take \$15.48 and divide it by 12 which will give you about \$1.12 per pen. Whenever they has you for the unit rate for anything, it means how much for 1 of that particular item (Eg. 80km per hour).

Hi Emily,
For Question #7 of review #3, two lines are parallel if they have the exact same slope. For example, a line in the form y = mx + b, m = slope (rise/run) and b = y -intercept. When we are looking to compare to see if it is parallel or perpendicular then we just look at the slope (m) . If the slope is the same it is parallel (Eg./ Given the lines y = 2x + 6 & y = 2x – 8, m = 2 for both the lines, so these lines are both parallel). If the 2 lines are perpendicular, then the slopes are negative recipricols of each other (Eg./ Given the lines y = (2/3)x + 6 & y = (-3/2)x -5, m = 2/3 & m = -3/2 for these lines so they are perpendicular). For #7, y = 4x + 1 and y = (-1/4)x + 7, m = 4/1 and m = -1/4, so these lines are perpendicular. Hopefully this makes sense. If not, then I will be at school today (Jan 23) or on Mon Jan 26 and you can come see me for help. Have the office page me if you can’t find me.
