A new high school math project is being tested in the state. In the first year (year 1), there are 687 students involved. By the end of the third year (year 3), 12459 students are expected to be involved. Assuming the increase is linear, write the equation of the line, in slope-intercept form, representing the number of students
participating in this project for each year x. Use this result to predict the number of students involved at the end of 5 years.
Hint: Use the ordered pairs (1,687) and (3, 12459)
The equation of the line in slope-intercept form is
(Type an equation using x and y as the variable. Type your answer in slope-intercept form)
