Since the temperature keeps increasing by 2°F each hour for the next 7 hours, the graph will be a straight line graph.
Let T be temperature
t be the time at temperature T
At t₁ = 0, T₁ = 43°F
At t₂ = 1, T₂ = 45°F (temperature increase by 2°F)
Using the straight-line formula to get the equation of the graph. The equation is expressed as T = mt + b
- m is the slope
- b is the intercept
Get the slope
![m=\frac{T_2-T_1}{t_2-t_1}\\ m=\frac{45-43}{1-0}\\m=\frac{2}{1} \\m = 2](https://tex.z-dn.net/?f=m%3D%5Cfrac%7BT_2-T_1%7D%7Bt_2-t_1%7D%5C%5C%20m%3D%5Cfrac%7B45-43%7D%7B1-0%7D%5C%5Cm%3D%5Cfrac%7B2%7D%7B1%7D%20%5C%5Cm%20%3D%202)
Get the intercept
Substitute m = 2 and the coordinate (0, 43) into the expression
43 = 2(0) + b
43 = b
b = 43
Get the equation of the line
T = 2t + 43
