Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 2, hence
y = 2x + c ← is the partial equation
To find c substitute (- 4, - 9) into the partial equation
- 9 = - 8 + c ⇒ c = - 9 + 8 = - 1
y = 2x - 1 ← equation in slope- intercept form
