Question

Which equation represents the linear relationship shown in the table? y=3x+4 y=3x+8 y=8x+3 y=4x+3 x y 0 3 2 11 4 19 6 27

Answer 1

The linear relationship is given by, y = 4x + 3

Explanation:

The points given are ( as (x,y) pair)

x y

0 3

2 11

4 19

6 27

The given lines are ,

1) y = 3x + 4

2) y = 3x + 8

3) y = 8x + 3

4) y = 4x + 3

Now , by inspection or trial and error method only line (4) does satisfy all the points, so the linear relationship is given by,

y = 4x + 3
