Given:
The given equation is

where x is height in feet and y is weight in pounds.
Required:
We need to find the representation of the y-intercept.
Step-by-step explanation:
The given equation is of the form

where b is the y-intercept.
We get b =-132.
We know that the y-intercept is the value of y when x=0.
The value of y represents weight in pounds and x is the height in feet.
The weight of the adult is -132 pounds with zero height.
Final answer:
The y-intercept of this function represents the weight of the adult is -132 pounds with zero height.
