Answer:
y = 2x - 20
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 (9, - 2) into the partial equation
- 2 = 18 + c ⇒ c = - 2 - 18 = - 20
y = 2x - 20 ← equation in slope- intercept form
