Answer:
y = 5x - 6
Explanation:
The equation is in the form
y = mx + c ( m is the rate of change and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (3, 9) ← ordered pairs from the table
m =
=
= 5
The line crosses the y- axis at (0, - 6) ⇒ c = - 6
y = 5x - 6 ← linear equation
