A school has 4820 students. Five years later, the same school has 3850 students. If there was linear growth, the slope of this line would (numerically) be -194 (negative 194). Explain what this means. The number of students at the school decreased by 194 each year. The number of students at the school decreased by 194 every four years. Every 194 years, there will be one fewer student at the school. The number of students at the school increased by 194 each year. The number of students at the school increased by 194 every four years.

Question
Transcribed Image Text:A school has 4820 students. Five years later, the
same school has 3850 students. If there was
linear growth, the slope of this line would
(numerically) be -194 (negative 194). Explain what
this means.
O
The number of students at the school
decreased by 194 each year.
The number of students at the school
decreased by 194 every four years.
Every 194 years, there will be one fewer
student at the school.
The number of students at the school
increased by 194 each year.
The number of students at the school
increased by 194 every four years.
Transcribed Image Text:Based on the coefficient of determination (R²
)value given for Graph A, which is the best
possibility of the coefficient of determination (R²
) for Graph B?
