Answer:
[tex]y=-\frac{1}{4} x+6[/tex]
Step-by-step explanation:
To find the perpendicular line of y=4x-5 you need to substitute to its slope (4), the anti-reciprocal number (-1/4).
Now you know the slope of the second line let's find the y-intercept (which is the point 0,6):
[tex]y=-\frac{1}{4} x+6[/tex]
