Question

Jace gathered the data in the table. He found the approximate line of best fit to be y = –0.7x + 2.36.



What is the residual value when x = 5?

–3.14
–0.86
0.86
3.14

Answer 1

Okay but I'm like lowkey positive the answer is -1.14

y = -0.7x + 2.36
x = 5

y = (-0.7 x 5) + 2.36
y = -3.50 + 2.36
y = -1.14

Answer 2

Answer with explanation:

The Approximate line of best fit is given by the equation:

    y = –0.7 x + 2.36

We have to find , value of ordinate that is y, when ,abscissa is 5.

Putting , x=5 , in the above equation ,to get the value of y

 y = -0.7 × 5 + 2.36

   = -3.5 +2.36

  = -1.14

→None of the option.

if the equation has been like this

y = -0.7 x +0.36

y = -0.7 × 5 + 0.36

   = -3.5 +0.36

   = -3.14

Option A: -3.14
