Answer:
Step-by-step explanation:
1. 2x + 3y = 1,470
β2x β2x
3y = β2x + 1,470
3y/ 3 = β2x/3 + 1,470/3
y = β2x/3 + 490
The y-intercept of this equation is 490 and the slope is -2x/3.
2. I would graph this line by finding the y-intercept 490 first.
Then, you would move down twice from 490 to 488.
Finally, you would move to the right 3 times.
3. F(x) = β2x/3 + 490
