Answer:

y = - 3x - 1

Explanation:

The equation in slope- intercept form is

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

Calculate m using the slope formula

m =
(y_(2)-y_(1) )/(x_(2)-x_(1) )

with (x₁, y₁ ) = (1, - 4) and (x₂, y₂ ) = (2, - 7) ← 2 ordered pairs from the table

m =
(-7+4)/(2-1) =
(-3)/(1) = - 3 , thus

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

To find c substitute any ordered pair into the partial equation

Using (1, - 4 ), then

- 4 = - 3 + c ⇒ c = - 4 + 3 = - 1

y = - 3x - 1 ← equation of linear function
