Answer:
The increase in temperature is [tex]0.8\°C[/tex]
Step-by-step explanation:
we know that
The formula to calculate the rate or slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have
[tex]A(11,23.8)\ B(13,25.4)[/tex]
Substitute the values
[tex]m=\frac{25.4-23.8}{13-11}[/tex]
[tex]m=0.8\frac{\°C}{cycle\ per\ second}[/tex]
therefore
The increase in temperature is [tex]0.8\°C[/tex]
