Find Slope :
--------------------------------------------------
y = -2/7x + 9
Slope = -2/7
Perpendicular slope= 7/2
--------------------------------------------------
Find y - intercept :
--------------------------------------------------
y = mx + b
y = 7/2 x + b
At (4, -6)
-6 = 7/2 (4) + b
-6 = 14 + b
b = -6 - 14
b = -20
--------------------------------------------------
Form equation :
--------------------------------------------------
y = mx + b
y = 7/2 x - 20
2y = 7x - 40
--------------------------------------------------
Answer: 2y = 7x - 40

Answer:
18 ounce package for $6.30
Step-by-step explanation:
For each one, you divide the money by the package to see how much it is per ounce.

Step-by-step explanation:
-7 squared is 49
49 × 2 = 98
12-98= -86
.45 * 120 = 54
.072 * 54 = 3.888
54 + 3.888 = 57.888= $57.89
