Find the slope and equation of a line perpendicular to the y axis that passes through (3,-8)

A line perpendicular to the y axis is horizontal line (parallel to the x axis).

Equation of this line is y = a.

The line passes through (3, -8) → x = 3 and y = -8.

Therefore your answer is y = -8.

$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

probably .5

i can on others if necessary.
