Step-by-step explanation:
Given:
Two points are A(6,1) and B(9,4).
To find:
The equation of the line that passes through the given points.
Solution:
If a line passes through two points and , then the equation of the line is:
It is given that the line passes through the two points A(6,1) and B(9,4). So, the equation of the line is:
Adding 1 on both sides, we get
Therefore, the equation of the line is .
