Question

Which of the following is the equation that represents the function given in the table?

x y

–2 16

–1 11

1 1

2 –4

1. Y= -1/5/x+6

2. Y=6x-1/5

3. Y=-5x+6

y=6x-5

Answer 1

3. y=-5x+6.

Explanation:

if to substitute given coordinates into equations and check equalities, then

y(-2)=-5*(-2)+6=16;

y(-1)=-5*(-1)+6=11;

y(1)=-5*1+6=1;

y(2)=-5*2+6=-4.

It means correct answer is 3.
