E = { x/ x is an even positive integer less than 10 }
(c) E = { x / x is positive integer, x< 10 and x is a multiple of 2}
(2) F = { 3, 6,9, 12, 15 , …}
(a) F = {x/ x is appositive integer that is divisible by 3}
(b) F = {x/x is a multiple of 3}
(c) F = {x/x is a natural number that is divisible by 3}

1. A = {x/x2 + x – 6 } and B = { -3,2}. Is A = B?
2. A = {x/x is prime number which is less than 10} and B = {x/x2 – 8x + 15 = 0}
   (a) Is A = B (b) Is B⊂ A?
3. P = {x/x is an integer and -1 < x<3/5 }and Q = {x/x3 -3x2 + 2x
   also the slope of median.
4. The vertices of parallelogram are the points R(1,4), S(3,2), T(4,6), V(2,8). Find the slope of
   each side.
5. Determine the slope of each side of the quadrilateral whose vertices are A(5,6), B(13,6),
   C(11,2). Can you tell what kind of quadrilateral it is?
6. A quadrilateral has as vertices the points M(a,b), N(c,d), Q(c+d,e), P(a+d,e). Find the slope
   of each side.
7. C is the mid-point of AB, A if the point (-3,-2), and B is the point (2,8
