Answer 1

Answer:

-3x-3

Step-by-step explanation:

Answer 2

Answer:

y = - 3x - 3

Step-by-step explanation:

the equation of a linear function in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (6, -21) ← 2 points from the table

m = $\frac{-21-3}{6+2}$ = $\frac{-24}{8}$ = - 3

y = - 3x + b ← is the partial equation

To find b substitute any other point from the table into the partial equation

using (2, - 9), then

- 9 = - 6 + b ⇒ b = - 9 + 6 = - 3

y = - 3x - 3 ← linear relationship
