Question

How do you find the line that passes through (4,3) and (5,8)?

Answer 1

`5x-y=23`

Explanation:

We can solve this equation using the 2 point general formula which is
`y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)`
where `(x_1,y_1)=(4,3)` and `(x_2,y_2)=(5,8)`

So,
`y-3=(8-3)/(5-4)(x-4)`

Solving this should be easy now)
