A <em>linear function</em> has the following format:
In which:
- m is the slope.
- b is the y-intercept.
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.
