Question

What is the equation of the line between `(10,3)` and `(7,-9)`?

Answer 1

I found: `y=4x-37`

Explanation:

We can use the relationship between the coordinates of point 1 and 2 as:
`(x-x_2)/(x_2-x_1)=(y-y_2)/(y_2-y_1)`
or:
`(x-7)/(7-10)=(y+9)/(-9-3)`
`(x-7)/-3=(y+9)/-12`
`-12x+84=-3y-27`
`3y=12x-89`
`y=4x-37`
