Answer:

see explanation

Explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (0, 340) and (x₂, y₂ ) = (4, 292) ← 2 ordered pairs from table

m =
(292-340)/(4-0) =
(-48)/(4) = - 12

(0, 340 ) → gives the y- intercept b = 340

The equation is of the form

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

y = - 12x + 340
