Which of the following ordered pairs could be placed in the table and still have the relation qualify as a linear function?
2 answers:
Linear functions have to have the same slope between any 2 points find the slope betwen them slope betwen 2 points (x1,y1) and (x2,y2) is (y1-y1)/(x2-x1) given (1,12) and (3,9) slope=(9-12)/(3-1)=-3/2 if we wanted to chek furthere, we check (3,9) and (5,6) and fnd that the slope is also -3/2 so y=mx+b m=slope b=yint y=-3/2x+b find b if x=1 then y=12 12=-3/2+b add 3/2 both sides 12+3/2=b 13+1/2=b 26/2+1/2=b 27/2=b y=-3/2x+27/2 try them we have 2 x values 7 and 3 input them and see their outputs for x=7 y=-3/2(7)+27/2 y=-21/2+27/2 y=6/2 y=3 (7,3) is a valid point for x=3 hold a second, we already have a x=3 it is (3,9) none of them answer is (7,3)
Answer:
Your answer would be A (7,3)

1/5 because there are 7 numbers divisible by 5 from 1 to 35. 5,10, 15, 20,25,30,35, and out of those there are 35 cards, 7 out of 35 or 7/5 can be simplified to 1/5.
The answer would be 35 99/100 because you cannot simplify 99/100
Answer:
8x-4=x+10
8x-x = 10+4
7x = 14
x= 14/7
x= 2
