What is the slope
5x+4y=4
4x+5y=8

is it -5/4 and 4/5
Answered by drwls
Neither of your answers is right. They both have the same slope, -4/5. Rewrite each in y = mx + b form to see why

Sorry, I have to correct you drwls
the slope of 5x + 4y = 4 is -5/4
the slope of 4x + 5y = 8 is -4/5

Answered by drwls
Blame my dyslexia. I misread the second one as 4y + 5x = 8 . You are right

Thank you Cianan for catching and reporting my error. I'm sorry Bryan; I will try to be more careful in the future
