To make their parties even more irresistible to little kids, Kat and Xander decided to add tethered balloon rides as an option for parents. The balloon holds 10 people, rises quickly to the maximum tether height of 50 meters, then slowly and steadily descends to the ground. As they tested their balloon, the pair took measurements to ensure a safe, smooth, and fun ride. Two of the measurement points in (x, y) format, where x represents minutes in descent and y equals elevation (in meters) are (1, 45) and (4, 30). What is the y-intercept of this line?

The Y intercept C = 50m

Step-by-step explanation: The graph is a negative one because it has a negative slope (gradient).

Using general linear equation formula Y = MX +C

The graph equation will be:

Y = -5X + 50
