The analysis of a data set last year produced a line of best fit with equation y = 2.108x - 0.3818. Data was collected from the same sample this year and produced a line of best fit with equation y= 2.107x + 1.7455. Explain the vertical
change in going from last year's data to this year's data.

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters

Determine the standard form of the equation of the line that passes through (-2,0) and (8,-5)
