I need help can someone figure these out?

1) y= 25x+50

2) y= -2,000x+30,000

3) y= 1.5x+5

Step-by-step explanation:

In each equation, there is a set amount (50 dollars, 30,000 feet, and 5 centimeters) and an amount that is influenced by another variable such as time(25 dollars, 2,000 feet, 1.5 centimeters). Hope this helped :)
