Answer:
They are both linear
Step-by-step explanation:
1.
Use rise/run to find the slope of the line.
rise=21.8
run=1
therefore, the slope is 1/28. You can use that to graph the line. If the line meets the points on your table, it is linear. It does. The equation of the line would be y=21.8x.
2.
We can use the same process as before.
rise=7
run=2
Therefore, slope is 7/2. When this line is graphed it meets all the points, so it is linear.
Alteratively, you could graph the points first and then see if you get the same slope.
