Given:

The given equation is


y=48.8x=132

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


y=mx+b

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.
