Answer:
y = - x + 2
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 = - 1, thus
y = - x + c ← is the partial equation
To find c substitute (4, - 2) into the partial equation
- 2 = - 4 + c ⇒ c = - 2 + 4 = 2
y = - x + 2 ← equation of line
