Graph the line with the equation y = -x - 1.

This is a straight line. We only need 2 points to graph a straight line.

Let x = 0

y = -(0) - 1

y = -1

Our first point is (0,-1).

Let x = 1

y = -(1) - 1

y = -2

Our second point is (1,-2).

See attachment for graph.

71° F

Step-by-step explanation:

Consider the rational part of f(t)

 ( divide numerator and denominator by t³

=

As t → infinity then → 0 , the expression simplifies to

= = 40

Thus after driving for a long time

f(t) = 31 + 40 = 71° F
