Answer:
slope = 7
Step-by-step explanation:
x 1 2 3 4 5
y 3 10 17 24 31
The differences in x between consecutive points are all 1.
The differences in y between consecutive points are all 7.
Since for equal differences in x there are equal differences in y, this is a linear relation.
slope = (difference in y)/(difference in x)
Let's choose 2 points: (1, 3) and (5, 31)
slope = (31 - 3)/(5 - 1) = 28/4 = 7
slope = 7
