A new high school math project is being tested in the state. In the first year (year 1), there are 628 students involved. By the end of the third year (year 3), 12402 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, 628) and (3, 12402). .. . 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.) At the end of 5 years, students would be involved. (Type a whole number.)
