Did you figure out the answer
Answer : y = -3x + 2
From the table the x and y values can be grouped as ordered pairs
i.e (x,y)
(1,-1) ,(2,-4) , (3,-7) as (x1,y1) , (x2,y2) and (x3,y3) respectively
[(y-y1)/(x-x1)] = [(y3-y2)/(x3-x2)]
[(y-(-1))/(x-(1))] = [((-7)-(-4))/((3)-(2))]
(y+1)/(x-1) = (-7+4)/(3-2)
(y+1)/(x-1) = -3/1
Cross multiply
(y+1)=-3(x-1)
y+1 = -3x + 3
y = -3x + 3 -1
y =-3x + 2

Answer:
l = 24ft
Step-by-step explanation:
A = lw
360 = (x + 9)(x)
360 = x^2 + 9x
0 = x^2 + 9x - 360
0 = (x + 24)(x - 15)
x ≠ -24 (length cannot be negative)
x = 15
l = 15 + 9
l = 24ft
