Answer:
the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively
Step-by-step explanation:
The computation of the cost of one package of chocolate chip cookie and one package of ginger bread is shown below:
Let us assume the package of chocolate chip cookie be x
And, the package of ginger bread is y
So,
According to the question
6x + 2y = $72
6x + 10y = $216
Now subtract equation 1 from equation 2
-8y = -144
y = $18
And, for x it would be
6x + $36 = $72
x = $6
Hence, the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively
Answer:
-4
Step-by-step explanation:
Pick any two points, let's go with (-7, 21) and (-6, 17) to find slope:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (17- 21) / (-6 - (-7))
= -4 / 1
m = -4
---Extra info---
y-intercept using anyone point, let's use (-5, 13) and slope above:
y = mx + b
13 = -4(-5) + b
13 = 20 + b
b = -7
Equation of line:
y = mx + b
y = -4x - 7
Check:
(-7, 21)
y = -4x - 7
21 = -4(-7) - 7
21 = 21
(-4, 9)
y = -4x - 7
9 = -4(-4) - 7
9 = 9
