489 to the nearest foot.

Step-by-step explanation:

y = - 2.58x + 566.67

x = 30:

y = - 2.58*30 + 566.67

= 489 to nearest foot.

A 30 year old driver can see 489.27 feet

Step-by-step explanation:

The equation yˆ=-2.58x+566.67 models the distance a driver can see in feet, where x is the age of the driver in years.

WE need to find out the height when x is 30

Plug in 30 for x and find out y

y=-2.58x+566.67

Replace x with 30

y=-2.58 (30) + 566.67 = 489.27

A 30 year old driver can see 489.27 feet
