Graph the following equation using the point-slope method. Draw the point from the equation in yellow. Draw at least one additional point in red using the slope. 6. y - 7 = 3(x + 2)
7. y +4 = ½(x - 2)
8. y -2 = 3(x -2)
9. y - 1= (1/3)(x + 1)
10. y - 2= (-1/2)(x - 5)
15. At Generic High School, in the year 2001, there were 20 students per every computer. In 2008, there were 4 students per computer. Write two ordered pairs to represent the ratio of student to computer. (Let x equal the number of years since 2000.)
