What is the equation of the line passing through #(41,89)# and #(1,2)#?
1 Answer
Use the two coordinate formula and rearrange into the form
Explanation:
The Two Coordinate Formula
The general form of the two coordinate formula is:
when you have two coordinates,
Applied to your example
The values in your example are:
Substituting these into the formula we get:
If we evaluate the denominators we get:
We can then multiply both sides by -87 to get rid of one fraction:
Next we can multiply both sides by -40 to get rid of the other fraction:
Next we can take away 3560 from both sides to get
Next we can multiply by -1 to flip the signs:
Finally we divide by 40 to get
