Question

the pizzas temperature (in degrees celsius) as a function of time (in minutes) is graphed.
graph with time (minutes) on x - axis and temperature (deg - celsius) on y - axis, a line passing through points, asking: what was the pizzas temperature after 2 minutes?
\boxed{} degrees celsius

Explanation:

Step1: Identify slope of the line

First, use two points on the line: when $t=0$, $T=-5$; when $t=1$, $T=0$. The slope $m = \frac{0 - (-5)}{1 - 0} = 5$.

Step2: Define temperature function

The linear function is $T(t) = mt + b$, where $b=-5$. So $T(t)=5t-5$.

Step3: Calculate temp at t=2

Substitute $t=2$ into the function.
$T(2)=5(2)-5$

Answer:

10 degrees Celsius
