Answer:
y = - 2x + 13
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 of the line
To find c substitute (9, - 5) into the partial equation
- 5 = - 18 + c ⇒ c = - 5 + 18 = 13
y = - 2x + 13 ← equation in slope- intercept form
