Question

The endpoints of a side of rectangle ABCD in the coordinate plane are at A (3,9) and

B(5, 1). Find the equation of the line that contains the given segment.
The line segment is CD and point C is at (9,2).
The equation is

Answer 1

y = - 4x + 38

Explanation:

A(3, 9)

B(5, 1)

`m_(AB)` =
`(1-9)/(5-3)` = - 4

CD║AB

C(9, 2)

y - 2 = - 4(x - 9)

y = - 4x + 38
