Use the line of best fit to estimate the French score for a student who got 65 in maths.
just olya [345]

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:

y = mx + b

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:

m = \frac{26 - 65}{90 - 10} = -0.4875

Then:

y = -0.4875x + b

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

y = -0.4875x + b

65 = -0.4875(10) + b

b = 69.875

Hence:

y = -0.4875x + 69.875

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

y = -0.4875(65) + 69.875 = 38.1875

The estimated French score is of 38.1875.
