(−7,7)(-7,7) , (3,9)(3,9)
(1,2)(1,2) , (2,9)(2,9)
(7,9)(7,9) , (0,3)(0,3)
(100,588)
(2,4)(2,4) , (−3,−3)(-3,-3)
(1,1)(1,1) , (3,3)(3,3)
(12,12)(12,12) , (12,24)
For the first month, the membership fee deducted = $15
So, -15(1) will represent this situation.
Similarly, for the second, third, fourth months, the expressions will be:
-15(2), -15(3), -15(4) and so on.
Hence, if t represents the number of months, then -15t will represent ash's art club membership being deducted every month for a year.
Remark
I like to work from the original equation.

T = 2.2 seconds
pi = 3.14
L = ??
Substitute and Solve
T = 2*pi*sqrt(L/32) Find the value of 2*pi
2.2 = 2*3.14* sqrt(L/32)
2.2 = 6.28 * sqrt(L/32) Divide both sides by 6.28
2.2/6.28 = sqrt(L/32)
0.35032 = sqrt(L/32) Square both sides.
0.122723 = L/32 Multiply both sides by 32
0.122723 * 32 = L
L = 3.927 feet. <<<<< Length pendulum creating 2.2 seconds.
