The equation of line ab is y = 1 over3x - 1. write a equation of a line perpendicular line ab in slope-intercept form that contains point (4, -2).

asap !

and i need to also know how you got the answer. so much. (:

a .4y4

hope this !

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
