HELP ME

Step-by-step explanation:

grab two points from the line then subtract x with x and y with y and you will get a fraction which will be mx and -7 will be your b

y=(the answer you got)*mx*-7

this is how you sub then

1-1

2-3  and it will look like a fraction

i explained it better for you but you have to do the work so you can better understand it

(you can always find b by looking for the point on the y-axis the line crosses)

a. is correct

$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
