Answer:
A. [tex] y = -3x + 500 [/tex]
Step-by-step explanation:
Equation of the situation in slope-intercept form is given as [tex] y = mx + b [/tex],
Where:
y = height of the balloon in the air (feet)
x = time (secs)
m = rate at which the balloon is heading towards the ground = -3
b = y-intercept, which is the starting value = 500
Substitute m = -3, and b = 500 into [tex] y = mx + b [/tex]
The equation would be:
✔️[tex] y = -3x + 500 [/tex]
