M = (y₂ - y₁) / (x₂ - x₁)
Multiply each side by (x₂ - x₁): M/(x₂ - x₁) = (y₂ - y₁)
Add y₁ to each side: y₂ = M/(x₂ - x₁) + y₁
It is not linear, because the x value is cubed, creating a curved line, while a linear line is straight.
Answer:
4/5
Step-by-step explanation:
→ Rearrange to get into y = mx + c
5y = 4x + c
→ Divide everything by 5
y = 4/5x + c
Answer:
$22.68 (to the nearest cent)
Step-by-step explanation:
A 115% markup can be calculated in this way: 1.15($10) = $11.50.
Thus, the selling price is $10 + $11.50, or $21.50.
The price the customer must pay, including the 5 1/2% tax, is
1.055($21.50), or $22.68 (to the nearest cent)
