Answer:
y + 4x = 17
Step-by-step explanation:
Y= mX + C
y = 1/4x + 3
m= gradient= 1/4
The perpendicular gradient should be the negative reciprocal of the gradient we have now.
which is : -1÷(1/4) = - 4
Now for the perpendicular line equation, we have:
y = 1
x= 4
m= -4
y - y1 = m ( x - x1 )
y - 1 = -4 ( x - 4 )
y - 1 = -4x + 16
y +4x = 17
