Answer:
y = 3x - 11
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 = 3, thus
y = 3x + c ← is the partial equation of the line
To find c substitute (4, 1) into the partial equation
1 = 12 + c ⇒ c = 1 - 12 = - 11
y = 3x - 11 ← equation of line
