Question

The endpoints of a side of rectangle ABCD in the coordinate plane are at A (2,9) and

Answer 1

Answer:

y = $\frac{1}{2}$ x + 8

Step-by-step explanation:

A(2, 9)

B(6, 1)

$m_{AB}$ = $\frac{1-9}{6-2}$ = - 2

AB ⊥ AD ⇒ $m_{AD}$ = $\frac{1}{2}$

A(2, 9)

y - 9 = $\frac{1}{2}$ (x - 2)

y = $\frac{1}{2}$ x + 8
