Answer:

$\large\boxed{y=\dfrac{5}{3}x+9}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

From the table we have an y-intercept (0, 9) → b = 9.

Take other point from the table (-6, -1).

Calculate the slope:

$m=\dfrac{-1-9}{-6-0}=\dfrac{-10}{-6}=\dfrac{5}{3}$

Finally:

$y=\dfrac{5}{3}x+9$

Answer:

4x^3 - 15x^2 - 10x + 24

Step-by-step explanation:

FOIL (x-4)(4x^2+x-6)

= x(4x^2+x-6) -4(4x^2+x-6)

= 4x^3+x^2-6x-16x^2-4x+24

=4x^3-15x^2-10x+24
