Loren solved the equation 10 = StartFraction 19 Over 9 EndFraction (149) + b for b as part of her work to find the equation of a trend line that passes through the points (1, 130) and (10, 149). What error did Loren make? She should have solved 10 = StartFraction 9 Over 19 EndFraction (149) + b for b.
She should have solved 1 = StartFraction 19 Over 9 EndFraction (130) + b for b.
She should have solved 149 = StartFraction 19 Over 9 EndFraction (10) + b for b.
She should have solved 130 = StartFraction 9 Over 19 EndFraction (1) + b for b.
