25 Go across to 3 on the weeks line, then look at how high the dot is.
34 Find 8 on the height line, then look straight across to the dot and read the weeks.
4Graph 3 Weeks go across, so 2 is the across number. Height goes up, so 5 is the up number.
5True The dot is 3 across and 6 up: 3 weeks and 6 dollars.
6False The dot is 3 across and 6 up: that is 3 weeks and 6 dollars, not 6 weeks and 3 dollars.
