The equation for the x (-1,0,1) and y (15,18,21) is y=3x+18, which is mentioned option B, this equation represent all the table values.

Step-by-step explanation:

The given values are,

x ( -1,0,1 )

y ( 15,18,21 )

Step:1

Check the values for Equation, y=18x+3

Substitute x = -1 and y = 15

15 = ( 18 × -1 ) + 3

15 = ( - 18 +3 )

15 ≠ -15..........( option A not represent)

Check for values for Equation, y=3x+18

Substitute x =-1 and y = 15

15 = ( 3 × -1 ) +18

15 = 15.............( option B represent the values)

Substitute next table values, x= 0 and y =18

18 = ( 3 × 0 ) + 18

18 = 18.............( option B represent the values)

Substitute the next table values, x=1 and y = 21

21 = ( 3 × 1 ) + 18

21 = 21.............( option B represent the values)

Check for the equation, y=-3x +18

Substitute the x=-1, y =15

15 = ( -3 × -1 ) + 18

15 ≠ 21..........( option C not represent)

Substitute the next table values

Check for the equation, $y= \frac{1}{3} x+18$

Substitute the x=0, y=15

15 = ( $\frac{1}{3}$ × -1 ) + 18

15 ≠ 17.6667..........( option D not represent)

Result:

The equation for the x (-1,0,1) and y (15,18,21) is y=3x+18, this equation represent all the table values.
