Answer:
y = 2x - 9
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 (4, - 1) into the partial equation
- 1 = 8 + c ⇒ c = - 1 - 8 = - 9
y = 2x - 9 ← equation of line
