Help!! Definate Medal!!!
Which lines are perpendicular to 5x + 4y = 8?
Choose all answers that are correct.
4y=5x+4
4y= 5x + 12
5y = 4x + 15
5y = –4x – 15
My answer is 4y=5x+4.. what do you think

Best ResponseYou've already chosen the best response.0first write the equation as y = mx +b the value m is the slope of th eoriginal line all perpendicular lines will have slope = 1/m

Best ResponseYou've already chosen the best response.0you need to show some work  otherwise you can just guess all 4 until I say... what is the slope of the original line? then  what is the slope of any perpendicular line..?

Best ResponseYou've already chosen the best response.0No I wasn't guessing all 4 ., you asked me to rewrite the equation in the formula y = mx +b so i did and i wanted you to take me from there.

Best ResponseYou've already chosen the best response.0OK so slope of original line is 5/4 and so the slope of any perpendicular line is 1/m 1 /(5/4) = 4/5 so which of the answer options has a slope of 4/5? (hint  the offset value i.e. the constant number does not affect the slope or answer....)
