How do you write an equation of a line through: (2,4) and (5,1)?
To write this equation we can use the point-slope formula. To use this formula we must first determine the slope.
The slope can be found by using the formula:
Using the two points given in the problem the slope is:
Now we can use the point-slope formula to determine the equation:
The point-slope formula states:
Using the slope we calculate and one of the points gives:
