Answer:
A
Step-by-step explanation:
Sales tax is a certain percent of a bill that is taken and sent to the state. Example: Florida sales tax is 7% of the total.

y - y₁ = m(x - x₁)
y - (-10) = -1⁴/₂₁(x - 6)
y + 10 = -1⁴/₂₁(x) + 1⁴/₂₁(6)
y + 10 = -1⁴/₂₁x + 7¹/₇
- 10 - 10
y = -1⁴/₂₁x - 3¹/₇
A proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0,0).
