Answer:
B and D
Step-by-step explanation:
to calculate the slope m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
(4)
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (3, - 1) ← 2 points from table
m = =
= 1 → B
(5)
with (x₁, y₁ ) = (- 1, - 4) and (x₂, y₂ ) = (2, 5) ← 2 points from table
m = =
= 3 → D
