Answer:
3x - 5y = 10
Step-by-step explanation:
Here's a fast but perfectly valid way to solve this problem:
Start with 3x-5y=25 ; replace that constant, 25, with C:
3x - 5y = C
Now plug in y = -5 and x = -5, obtaining:
3(-5) - 5(-5) = C
Then -15 + 25 = 10, and so C = 10, and:
3x - 5y = 10 is the desired equation of the new line.
