Question

A feather blew out of a bird nest 10 feet in the air. It drifted to the ground at a constant rate of 2 feet per second. Write an equation that shows the relationship between the elevation of the feather, y, and the number of seconds it has been falling, x

Answer 1

The question is an illustration of a linear function, and the equation that represents the function is $y =-2x +10$

A linear function is represents as: y = mx + c, where:

• m represents the slope or rate
• c represents the y-intercept

In this case, we have:

• $m = -2$

• $c = 10$

So, the equation becomes

$y =-2x +10$

Hence, the equation of the function is $y =-2x +10$
