Question

At the beginning of a week, a stock’s price is $9.40 per share. For that entire week, the stock’s price decreased at a steady rate of $0.20/day. Christine graphs the price of the stock versus time. She plots the price of the stock along the vertical axis, and she plots time in days along the horizontal axis.

What is the y-intercept of the line?

Answer 1

when
x=0
, i.e day 0
y=9.4
so the function starts at
9.4
and decreases linearly from then on,
9.4
is the y intercept.
