Question 843174
4x - y = 3 become
y = 4x -3
The slope of the perpendicular is the negative inverse of 4
so we want 4*inverse = -1
inverse = -1/4
Using y = mx + b as a template with m = -1/4 , x= -5 and y = 6
6 = (-1/4)(-5) + b
6 = 5/4 + b
subtract 5/4 from each side
4 3/4 = b
Our equations is y = (-1/4)x + 4 3/4
Let me know if this helps.
