A. 2x + 8y = 10

B. 2x – 8y = 8

C. 2x + 8y = 16

D. 2x – 8y = 16

Answer 1

since it crosses (0 2) and (8 0)
so substitute the two points into the equation

Answer 2

when x=0 only c would make you get y=2

Answer 3

wait what ?

Answer 4

:/

Answer 5

since (0,2) is on the line,
put x=0 into those equations, then you can see only 2x+8y=16
gets y=2

Answer 6

oh ok thank you :)

Answer 7

if there are more than one equation that match,
put x=8 into them to see which can get y=0
The answer will be the one that can match both (02)and(80)
no thanks ^^

Answer 8

He is correct do you know how to do this @Louis_Tomlinson_Girl ? How he got that answer?
