1) -3y+4 > 7y-3 over 6
2) 3y over 2 + 5 over 3 < -7y+2 over 4
3) If A(1,2) B(-2,6) and P(4,p) are collinear, find p.
THANK YOU!
1) and 2) are the same kind of problem, I will do the second one
3y/2 + 5/3 < (-7y+2)/4
multiply each term by 12 , the LCD
18y + 20 < -21y + 6
39y < -14
y < -14/39
3) slope AB = slope AP
4/-3 = (p-2)/3
times 3
-4 = p-2
etc
