1) Equation of the line Slope, m = [-2 -1]/[0 - 2] = -3 / -2 = 3/2y-intercept, b = -2 y = 3x/2 - 2
2) InequalityThe points over the line have y-coordinate greaetr than the value of the line, then y ≥ 3x/2 - 2 2y ≥ 3x - 4 3x - 2y ≤ 4 3) Answer: 3x - 2y less than or equal to 4.
If there are 30 students then each student would probably get called up 6 times. I did this by dividing 180 by 30 that got me so each student will go up at least 6 times if there are 30 students
