Answer:
y = 5/4x
Step-by-step explanation:
The given line is written in slope-intercept form. In this form, the slope is the coefficient of x, -4/5.
The perpendicular line will have a slope that is the opposite reciprocal of this value:
-1/(-4/5) = 5/4
The simplest such line is the one that goes through the origin:
y = 5/4x
