Answer:
y = - 2x - 18
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, thus
y = - 2x + c ← is the partial equation
To find c substitute (- 7, - 4) into the partial equation
- 4 = 14 + c ⇒ c = - 4 - 14 = - 18
y = - 2x - 18 ← equation of line
