Question

Still confused lol.

Complete the following ordered pairs for the equation.
6x + -5y = 20

(-5, _)
(_, -4)
(_, 2)

Answer 1

your points are ALWAYS in (x,y)

(-5,_)....-5 = x
now sub -5 in for x
6x + (-5y) = 20
6(-5) - 5y = 20
-30 - 5y = 20
-5y = 20 + 30
-5y = 50
y = -10
answer is (-5,-10)
any questions ?

Answer 2

Is it the signs that are confusing you ?

Answer 3

Yes, like i see what you did and then i try it and get confused. so the second one i would start it off like 6(-4) +-5y=20 ? because i wasn't sure if i use +-5 or just do -5

Answer 4

6x + (-5y) = 20 --- a + times a - = a negative.
so you could just use this equation : 6x - 5y = 20 for the rest of your problems

Answer 5

second one would start like this..
y = -4

6x - 5y = 20
6x - 5(-4) = 20

can you finish ? Don't forget a negative times a negative is a positive

Answer 6

yeah i got 20 so would i minus that by 20? because that would just be zero and then my answer would just be zero? it's just so confusing
