Let
t-------> the time in minutes
y------> the distance from home for an ant in feet
we know that

In this linear equation
the slope m is equal to

The y-intercept is equal to-------->

in this problem the y-intercept is the value of the distance in feet when the value of the time in minutes is zero
so
The y-intercept is equal to-------->

therefore
the answer is the option
D. The ant started out 2 feet from its home
