The answer for the first one is (-2,-3) because if you put a point there, then it would make a right triangle and, if ou take the x term from the higher point and the y term from the lower point and put them togeteher, then you get (-2,-3)
if you mean directly proportional where x/y=k where is x goes up, y goes up as well so try them out
first one: x/y=k 1/11=k does 3/23=k as well? no so this is not proportional
second one: x/y=k 1/2=k does 3/-10=k as well? no, so this is not proportional
third one: x/y=k 1/-6=k does 3/-22=k asl well? no, so this is not proportional
fourth one: x/y=k 1/-8=k does 3/-24=k as well? yes, so this is the proportiona one
subsitute
if x=1 and y=7
try the first
7=1+7
false so the first one doesn't work
try the second
7=1-7
false, so the second one doesnt' work
third
7=1/7
false so the third one doesn't work either
try the fourth
7=(7)(1)
7=7
true so this is the naswer
7=7 tue

Answer: y = -8
Step-by-step explanation: that is the definition of inequality difference in size, degree, circumstances, etc.; lack of equality.
" inequality"
Answer:
AIHC
Step-by-step explanation:
‘a’ is a variable
so this means something multiplied by 1/2 = 11
to solve we will divide both sides by 1/2 to isolate ‘a’
so a= 22
you can verify by plugging 22 into a
so
(1/2)(22)=11
which is true
