4-2 Writing Equations in Slope-Intercept Form
( 4, 2), slope
Find the y-intercept.
Write the equation in slope-intercept form.
In 2001, there were about 56.1 thousand golden retrievers registered in the United States. In 2002, the
number was 62.5 thousand.
Write a linear equation to find the number of golden retrievers G that will be registered in year t, where t = 0 is
the year 2000.
Graph the equation.
Estimate the number of golden retrievers that will be registered in 2017.
a. Two points on the line are (1, 56.1) and (2, 62.5). Find the slope of the line.
Let t be the number of years after 2000. Use the slope-intercept form and one of the points to find the y-intercept for
t = 0 year, 2000.
