plzz help

OpenStudy (hockeychick23):

Which of the following points are NOT on the graph of y = -4x + 4? (1, 0) --> 0= -4(1)+4 --> this is correct because it does equal zero (2, 4)--> 4= -4(2)+4--> this is NOT correct because it equals -4 not 4 (0, 4)--> 4= -4(0)+4--> this is correct because it equals 4 (-1, 8)--> 8= -4(-1)+4--> this is correct because it equals 8

OpenStudy (anonymous):

which one is it then

OpenStudy (hockeychick23):

(2,4)

OpenStudy (anonymous):

its just a matter of subbing... y = -4x + 4 now sub in your answer choices (x,y) and see which ones come out false. Which ones do not come out equal are your correct answers

OpenStudy (anonymous):

I DONT KNOW !!!!

OpenStudy (hockeychick23):

i already did it for you and told you the answer

OpenStudy (anonymous):

so its 1,0

OpenStudy (hockeychick23):

(1, 0) --> 0= -4(1)+4 --> this is correct because it does equal zero (2, 4)--> 4= -4(2)+4--> this is NOT correct because it equals -4 not 4 (0, 4)--> 4= -4(0)+4--> this is correct because it equals 4 (-1, 8)--> 8= -4(-1)+4--> this is correct because it equals 8 I said (2,4)

OpenStudy (anonymous):

ok don't get sasy with me @hockeychick23

OpenStudy (anonymous):

opi.....you are looking for the ones that do not equal.....so that would be (2,4) because... y = -4x + 4 (2,4)...x = 2 and y = 4 now sub 4 = -4(2) + 4 4 = -8 + 4 4 = -4 --- not correct....not on the line

OpenStudy (anonymous):

B is correct
