Answer:
y = - 1.5x + 9
Explanation:
since the table represents a linear function it has the form
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope- formula
m =
with (x₁, y₁ ) = (0, 9) and(x₂, y₂ ) = (4, 3) ← 2 ordered pairs from the table
m =
=
= -
= - 1.5
the ordered pair (0, 9 ) indicates that c = 9
y = - 1.5x + 9 ← equation of linear function
