Question

What is the graph of 6x+3y=18?

Answer 1

6x+3y=18

6*0+3y=18 ... plug in x = 0

0 + 3y = 18

3y = 18

y = 18/3

y = 6

so when x = 0, the value of y is y = 6

this means that the point (0,6) is on the line

Answer 2

now plug in y = 0

6x+3y=18

6x+3*0=18

6x+0=18

6x=18

x=18/6

x=3

which means that the point (3,0) is also on the line

Answer 3

so which graph

Answer 4

you tell me

which graph has both points (0,6) and (3,0) on the line?

Answer 5

the third one ?

Answer 6

correct, the third graph is the answer

Answer 7

thanks
