Answer:

Explanation:

First, find the slope of 4x - 5y = 7

Simplify it down to a readable form:

5y = 4x - 7

y = (4x - 7)/5

y = 4/5 x - 7/5

slope = 4/5

slope perpendicular to 4/5 is its opposite reciprocal, which would be -5/4.

given the point (2,3), we can get the equation using point slope form for linear equations: y-k = m(x-h) for point (h,k).

now plug:

y-3 = (4/5)(x-2)

y-3 = (4/5)x - 8/5
