Answer:

Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
First rewrite the equation of the given line in the form of y=mx +c.
4x+5y=25
5y= -4x +25

The gradient of the given line is 
The product of the gradient of perpendicular lines is -1.

Thus, m= 

Substitute a coordinate to find c.
When x= -4, y= -6,

Hence, the equation of the line is
