What is the slope
5x+4y=4
4x+5y=8
is it 5/4 and 4/5

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

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
