With this table of values:

X     Y 

-8   -15

-5   -12

-1   0

0     2

2     3

4     8

7     20

10   15

 

What's the approximate value of y when x = -3? What's the approximate value of x when y= -20?

Thanks!

We can geneate  a  liunear regression  approximation   using this website  : :   https://www.socscistatistics.com/tests/regression/default.aspx

 

The equation is

 

y = 1.58095 x - 1.12975

 

When x  = -3.....the approximate value fo y  is   -5.8726  ≈  -5.9

 

When x  = -20    .....the  approximate  value  for  y   is   -32.7488  ≈  -32.7
