Question

The endpoints of a side of rectangle ABCD in the coordinate plane are at A(1,4) and

B(4,1). Find the equation of the line that contains the given segment.
The line segment is AB.
The equation is y =

Answer 1

y = - x + 5

Explanation:

A(1, 4)

B(4, 1)

`m_(AB)` =
`(1-4)/(4-1)` = - 1

y - 1 = - 1 ( x - 4 )

y = - x + 5
