Paul recorded at regular intervals the temperature of a substance that was being heated. The data can be modeled by a linear equation: t = 2m + 40. The temperature is represented by (t) in degrees Celsius for a substance that had been heated for m minutes. In the equation: t = 2m + 40, what does the 40 represent?

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
