Explanation:
To find the expression of the<em> high temperature of the day (T) as a function of the day (t)</em>, analyze the trend shown on the table.
The data in the column of the day (t) increases by 1, and the the data in the column of the high temperature increases by 1.
Thus, the slope is 1ºF per day.
The point-slope form of the equation of a line is:
Where m is the slope and y₁, x₁ are the coordinates of any point on the line.
Using the point (2, 96) you get:
Using the names T and t for y and x, respectively:
Using the midpoint concept, it is found that the value of a is of a = 2.
<h3>What are the coordinates of the points?</h3>
Researching this problem on a search engine, the coordinates are given as follows:
<h3>What is the midpoint concept?</h3>
The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
Hence the following system of equations can be built:
(b + 1 + 2a)/2 = 3.
b + 1 + 2a = 6.
b = 5 - 2a.
(a + 2 + 3b + 3)/2 = 5
a + 3b + 5 = 10
a + 3b = 5.
Since b = 5 - 2a, we have that:
a + 15 - 6a = 5.
5a = 10
a = 10/5
a = 2.
The value of a is of a = 2.
