Answer: 5(x+1) -2(y-3) = 0

Step-by-step explanation: For a given line ax+by=c and point (h, k), a perpendicular line through the point can be written as ...

b(x-h) -a(y-k) = 0

A graphing calculator shows the point of intersection of the graphs of the two lines to be (x, y) = (-1, 3), so the line perpendicular to 2x+5y=5 through that point can be written ...

5(x+1) -2(y-3) = 0
