Answer:
y = 5x - 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
Here m = 5 , then
y = 5x + c ← is the partial equation
To find c substitute (3, 4) into the partial equation
4 = 15 + c ⇒ c = 4 - 15 = - 11
y = 5x - 11 ← equation of line
