Hello!

To find the percent tax, use the equation:

Substitute in the given values:

Multiply by 100 to find the percent tax:

I got 5 on it pull up n get 10
<span> 3a^3+8a-6
+4a^2-9a+11
=3a^3+4a^2-a+5

Point-slope form: y - y₁ = m(x - x₁)
[m is the slope, x₁ and y₁ ---> (x₁, y₁) is the point]
Since you know:
m = 5
(2, 6) = (x₁, y₁) Substitute/plug in the values into the equation
y - y₁ = m(x - x₁)
y - 6 = 5(x - 2) The 1st option is your answer
