Let's give the variable that you are trying to answer for a symbol. Let's call it X.
X = the amount of money both Greg and Thomas had in October
We know that in November, Greg added $120 to his account. So, Greg's account has: X + 120
We know that Thomas increased the money in his account by 20%, so Thomas' account has: X + 0.2X, or 1.2X
We know that these two amounts are equal:
X + 120 = 1.2X
Solve for X:
X + 120 - X = 1.2X - X
120 = .2X
120 / .2 = .2X / .2
600 = X
Y= -2/3x +26/3
First find the slope of the given points. The use the opposite reciprocal for the new slope. Find the midpoint of the given points. Use this ordered pair with your new slope. Plug into y=Mc+b to find b. Then rewrite using the new m and b.
