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

Answer:
$166.42.
Step-by-step explanation:
We have been given that the price of the cell phone is expected to increase by 165% in September 2015. The current price of a cell phone is $62.80.
The price of cell phone in September 2015 will be $62.80 plus 165% of $62.80.




Therefore, the predicted cost of a cell phone in September 2015 will be $166.42.
Let s be the son's age 15 yeasr ago and m the mother's age that year.

We also know that:

Plotting vallues:

Remember that they were that age 15 years ago.
So their actual age is 30 and 60.
