I hope this is good enough:
Let the number of cookies that kate eats be ‘n’
kate : n
nacy : 2n-4
avery : 2(2n-4)
n + 2n-4 + 2(2n+4) = 18
7n - 12 = 16
7n = 28
n = 4
kate : 4
nacy : 2x4 - 4 = 4
avery : 2(2x4 - 4) =8
Answer:
y = -1/3x - 5 1/3
Step-by-step explanation:
Slope Intercept =
y=mx + b
Substitute the Slope
y= -1/3x + b
Substitute x and y from the point into the equation
-6 = -1/3(2) + b
-6 = -2/3 +b
Isolate the b with the addition property of equality
-5 1/3 = b
Substitute all variables
y = -1/3x - 5 1/3
2/3 x 2 = 4/3 or 1 and 1/3
2/3 x 3 = 6/3 or 2
2/3 x 4 = 8/3 or 2 and 2/3
