MFM2P: Test #2 Review Sheet

	Please remember that Test #2 will be on Tuesday, March 27th, 2007.  Please be advised that you will be permitted to have water and use an MP3 player if necessary.  If you complete this sheet, you will be given a bonus mark on your test.

1) Graph the following by first putting into y = mx + b form and then using the y-intercept and slope.
a) 4x + 2y = 6		b) 3x – 3y = 9		c) 4x + 3y = 2

2) Algebra: Solve for x:
a) 3x + 4 = 10	b) -2x – 3 = 4		c) 1.5x + 3 = 2x	d) 0.23x + 1 = 2

e) 		f) 		g) 		h) 

3) Remember that y = m(x – p) + q is the point-slope equation for a line.  The slope is m, and the given point is (p, q).  Always put the equation into y = mx + b form.
Find the equation of a line
a) With slope -1 going through 		b) with slope 2.5 going through the 
the point (2, 3)				point (4, -1)

c) With slope -3 going through the	d) with slope 1.4 going through the
point (0, 2)					point (1,1)

4) Also this problem can be given if the slope isn’t given.  Remember that
slope = when two points are given and .  Then use the 
y = m(x – p) + q to solve the problem.
Find the equation of the line through the points
a) (-2, 3) , (4, -3)			b) (1, 1), (5, 9)

5) The last part of the test will be word problems.  They will deal with unit price, linear functions, and piecewise linear functions.  We will do a piecewise linear function problem and I will list a few others
Ashley works at a coffee shop earning $9 per hour.  When she works more than 30 hours, she gets “time and a half”
a) What does “time and a half” mean and what is her salary then?

b) Make a table of values to show her earnings for 0, 15, 30, 45, 60 hours
	Time		Earnings
	0	
	15	
	30	
	45
	60

c) How much will she earn if she works 41 hours this week?

6) Kyle is a tremendous golfer.  He played 5 games this weekend and scored 292.  If he is going for a week’s golf vacation and will play 21 games, what will his score be?

7) The amount of earnings that Mr. Sadler’s math class will have for its Share Lent is $5 plus 25 cents for each Popsicle sold.  
a) Write an expression for the earnings of our class.

b) If the class sells 31 popsicles, how much will we earn?

c) If we need $30.25 to beat Mr. Solinger’s class, how many popsicles must we sell?

8) Wayne Gretzky is 5 foot 11.  If there are 2.5 cm in an inch, how many cm tall is he?

9) Complete the chart.  The first one is done for you:
	Picture		Real Life			Scale
	5 cm			20 cm				1:4
	
10cm			30 cm			
	
	30cm			50cm

				25cm				1:5
