Answer:
Step-by-step explanation:
Divide sales tax amount over the item's cost
23.1 / 330 = 0.07
Therefore the sales tax is 7%
Slope intercept: y = mx + b
3y = 2x + 10
Y = 2/3x + 10/3
Perpendicular = opposite sign and reciprocal slope
Y = -3/2x + b
-10 = -3/2(10) + b
-10 = -15 + b, b = 5
Equation: y = -3/2x + 5
