Answer:
The equation of the line is
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
In which m is the slope and b is the y-intercept(the value of y when x = 0).
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
Line perpendicular to y = 4x + 4.
This line has slope 4, so our line will have slope:
So
Through (0, -3)
This means that
So
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.
