Answer:
y = 4x - 16
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 = 4, thus
y = 4x + c ← is the partial equation
To find c substitute (5, 4 ) into the partial equation
4 = 20 + c ⇒ c = 4 - 20 = - 16
y = 4x - 16 ← is the equation of the line
