Question

This graph shows how the population (in millions) increases over time.

1800 is the year 0.
which means years are counted after 1800
for example the year 1804 is the year 4.

1. Identify the slope of this linear model and explain its meaning IN CONTEXT.

2. identify y- intercept of the linear model and explain its meaning IN CONTEXT.

(I am interested in knowing what both of them mean IN CONTEXT)

years since 1800 population 50 127 160 2 174187 199 211 1 1.2 4 6 y = 0.0267x-0.0568 R2 = 0.7965 50 100 150 250 YEARS SINCE 1800

y=0.0267x-0.0568

1. Slope of the model is 0.0267 . This means that if year is increases by 1, population increases by 0.0267

2. y intercept is 0.0568 . This means that if year is 0, the population is -0.0586. which means years are counted at 1800
