Answer:

f(x) = 2x - 3

Step-by-step explanation:

x    y

Find the slope of the line that passes through (4, 10) and (2, 1).
Oksanka [162]

Answer:

slope = \frac{9}{2}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (4, 10) and (x₂, y₂ ) = (2, 1)

m = \frac{1-10}{2-4} = \frac{-9}{-2} = \frac{9}{2}

Basically you’re multiplying them both
(x^3 + 2x - 1)(x^4 - x^3 + 3)

so you need to make sure you multiply each one, if you do it right, you should end up with
x^7 - x^6 + 3x^3 + 2x^5 - 2x^4 + 6x -x^4 +x^3 -3

simplify by adding like terms
x^7 - x^6 + 2x^5 - 3x^4 + 4x^3 + 6x - 3

your answer would be the third option
