Answer:
C
Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
calculate m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (3,-5) ← 2 points from the table
m =
=
= - 2
note that (0, 1) is the y-intercept ⇒ c = 1
y = - 2x + 1 ← linear relationship → C
