Using a linear function, it is found that the estimated French score is of 38.1875.
A <em>linear function</em> has the following format:

In which:
Searching the problem on the internet, it is found that two points of the line of best-fit are: (10,65) and (90,26).
The slope is given by <u>change in the output divided by the change in the input</u>, hence:

Then:

Point (10,65) means that when
, and this is used to find b.



Hence:

For a student who got 65 in math, x = 65, and hence:

The estimated French score is of 38.1875.

<h3>What are fractions?</h3>
Fractions are non-integers that consist of a numerator and a denominator. A proper fraction is a fraction in which the numerator is less than the denominator. e.g. 2/3. A mixed fraction is made up of a whole number and a proper fraction. An example is 2 7/8.
<h3>How much lemonade did Regan sell?</h3>
2 7/8 x 2/3
23/8 x 2/3 = 23/12 = 1 11/12 gallons

Firstly this looks like translated log function graph
log1=0
As per graph the graph is pulled some inwards y axis but little bit
Usually log x leaves y axis at -1 but here it leaves at +2
So
y axis is moved upwards (+3)
Last function
