Answer:
First graph
Step-by-step explanation:
Here we have x ≥ 0, and y ≥ - 2, not x ≥ 0 and y ≥ 0. Thus, it doesn't restricts us fully to quadrant 1, but somewhat off considering y ≥ - 2. Now all we have to do is plot the following system of inequalities -
Convert each into slope intercept form -
Which should be bounded by a small region similar to graph 1! The shaded region represents each intersection with respect to their restriction to quadrant 1.

I would look through the numbers to determine their range. It appears to me to be 42 to 69. This suggests a frequency table with numbers 40 to 70, a range easily divided into 6 parts.
Since the width of each group will be (70 -40)/6 = 5, you have to decide on the group boundaries. It might work well to subtract 1/2 from the numbers 40, 45, 50, 55, 60, 65 to define the boundary. That way, for the integers given, you have
.. group 1 = 40 ≤ age < 45
.. group 2 = 45 ≤ age < 50
.. group 3 = 50 ≤ age < 55
.. group 4 = 55 ≤ age < 60
.. group 5 = 60 ≤ age < 65
.. group 6 = 65 ≤ age < 70
