Andrea’s work to find the equation of a trend line through the points (48, 61) and (72, 195) is shown below. Andrea’s Work Step 1 m = StartFraction 72 minus 48 Over 195 minus 61 EndFraction = StartFraction 24 Over 134 EndFraction = StartFraction 12 Over 67 EndFraction Step 2 61 = (StartFraction 12 Over 67 EndFraction) (48) + b Step 3 b = StartFraction 3,511 Over 67 EndFraction Step 4 y = StartFraction 12 Over 67 EndFraction x + StartFraction 3,511 Over 67 EndFraction What was the first error that Andrea made?
A- Andrea used the reciprocal of the slope.
B- Andrea made a computational error when she simplified m.
C- Andrea substituted incorrectly when she solved for b.
D- Andrea made a sign error when she solved for b.

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?
