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
