It would be the third option :)
In this problem, since we are trying to find Sam's monthly net income, we just need to multiply his weekly net income (which is after all the deductions come out) by how many times he gets paid! Because he gets paid 4 times, we just need to multiply $654.48 by 4! The you should get an answer of $2617.92, which is Sam's monthly net income!
It is 165 I hope this helps :)
slope intercept formula is y = mx + b.
Isolate the y. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 2x from both sides
2x (-2x) + 3y = (-2x) + 1470
3y = -2x + 1470
Isolate the y. Divide 3 from both sides
(3y)/3 = (-2x + 1470)/3
y = (-2x + 1470)/3
Simplify
y = (-2/3)x + 490
y = (-2/3)x + 490 is your answer
hope this helps
