Answer:
Left: yes it is linear
Right: No it is not.
Explanation:
Left Problem
The table on the left is linear. It's general form is
y = 6x + 7
x = 5
y = 5*6 + 7
y = 37
-------------------
x = 8
y = 6*8 + 7
y = 48 + 7
y = 55
------------------
y = 6*12 + 7
y = 72 + 7
y = 79
=============
Right Problem
The right problem looks like it is linear. It is not, I don't think. Do the same thing you did above.
y = 62x
x = 2
y = 2*62
y = 124
-----------------------
y = 62x
x = 6
y = 62 * 6
y = 372
---------------------
y = 62*x
x = 9
y = 62 * 9
y = 558
It should be 558 not 552
