a) 0, 4, 8, 12, 16
explanation- simply add 4 to the previous number. 0+4= 4, 4+4= 8, 8+4= 12, etc etc.
b) 0, 8, 16, 24, 32
explanation- the same as letter a.
c) if you multiply the top number (the x value) by two, then you will get the bottom number (the y value)
explanation- 0+0= 0, 4+4= 8, 8+8= 16, 12+12= 24, and 16+16= 32
d) (0,0), (4,8), (8,16), (12,24), and (16,32)
explanation- the first number comes from the set in letter a (the x value) and the second number comes from the set in letter b (the y value).
e) -
explanation- find a spare piece of graph paper and put the points down. for example, (4,8) would be four places to the right on the horizontal line (the x-axis), and then down 8 places, still staying in the four postion. so four over, eight down. the vertical line is called the y-axis.
Hope this will help somewhat :)
