The equation that shows the relationship between Amir's altitude relative to sea level (in meters) and time (in minutes) is y = -12x + 360
<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent Amir's altitude relative to sea level after x minutes. He was at sea level after 30 minutes, hence:
0 = -12(30) + b
b = 360
y = -12x + 360
The equation that shows the relationship between Amir's altitude relative to sea level (in meters) and time (in minutes) is y = -12x + 360
