Answer:
m=0.7404, b=3.9117m=0.7404,b=3.9117
y=0.7404x+3.9117y=0.7404x+3.9117
x=18x=18
y=0.7404(18)+3.9117=17.2389y=0.7404(18)+3.9117=17.2389
Residual
16-17.2389= -1.238916−17.2389=−1.2389

-9
the slope of the line is -9
The estimated amount would be 5.50 or 6 depending on what your estimating by and the actual answer would be 5.45. I hope this helped :)
