Okay,
the x values are on the ‹——› line.
the y values are on the | line
Where the darkest + happens, the very center is ∅, 0 for both x and y.
So, for each pair you found in 25, draw them on 26.
For (x=1,y=0): go 1 space to the right from ∅, the y value is 0 so just draw a dot on the _ line 1 space from ∅.
For (x=2,y=2): go 2 spaces to the right from ∅, the y value is 2 so, from that spot you just moved to, go 2 spaces up |, draw a dot.
For (x=3, y=4): go 3 spaces to the right from ∅, the y value is 4, so from where you just got to, go 4 spaces up |, draw a dot.
Now draw a straight line connecting the three dots.
The range means the y values.
What are the y values in your table?
The range is {0,2,4}
