Answer:
y = 11/20x -50
Step-by-step explanation:
100y−39,000=55(x−800)
Distribute
100y−39,000=55x−44000
Add 39000 to each side
100y−39,000+39000=55x−44000+39000
100y = 55x -5000
Divide each side by 100
100y/100 = 55x/100 - 5000/100
y = 11/20x -50
This is slope intercept form
where 11/20 is the slope and -50 is the y intercept
