Slope = 5
y = mx + b
2 =5(4) + b
b = 2 - 20
b = -18
<span>point-slope equation
y - 2 = 5(x -4)
</span><span>slope-intercept equation
y = 5x - 18
standard form
5x - y = 18</span>
When we divide the interval from 1 to 5 into 4 subintervals, each has a width of 1. Simpson's rule has us evaluate the integral as
... integral = (1/3)(f(1) +4f(2) +2f(3) +4f(4) +f(5)) = (1/3)(10 +4·25 +2·46 +4·73 +106)
... integral = (1/3)(600) = 200 . . . . . by Simpson's rule
_____
The integral evaluates to
_____
Simpson's rule uses a quadratic interpolation, so evaluates quadratics exactly.
