Answer:

y = 2x - 6

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 , then

y = 2x + c ← is the partial equation

To find c substitute (2, - 2 ) into the partial equation

- 2 = 4 + c ⇒ c = - 2 - 4 = - 6

y = 2x - 6 ← equation of line
