Take any 2 points through which the line on graph passes,
(0,-1) =(x₁,y₁)
& (2,-4)=(x₂,y₂)
slope=(y₂-y₁)/(x₂-x₁)
=[-4-(-1)]/(2-0)
=-3/2

Answer:
3.03
Step-by-step explanation:
x y
56 28
45 25
68 34
49 30
58 32
63 36
66 23
62 29
slope 0.174993175
Intercept 19.40977341

is the regression line
As per line, we can find y for x=68 as

For x=68
y actual = 34
y predicted = 30.97
Residual = 34-30.97
= 3.03
