Answer 2

Answer:

DISTANCE FORMULA : DISTANCE BETWEEN TWO POINTS P (X,Y) AND Q (A,B) IS GIVEN BY

_______________

PQ = √ (X - A)^2 + (Y - B)^2

Q1) Distance between (2,3) and (4,1)

= √(2-4)^2 + (3-1)^2

= √4 + 4

= √8

= 2√2

Q2). Coordinate of mid point of A(X1,Y1) and B (X2,Y2) is given by

(X1+X2)/2, (Y1+Y2)/2

Q3) Distance between (-6,8) and origin (0,0)

=√ (-6-0)^2 + (8-0)^2

= √36+64

= √ 100

= 10

Q4) Equation of a line parallel to 3x + 4y = 12 is

6x + 8y = 20

(note: there may infinite such equations, the only fact is that

3/6 = 4/8

i.e. coefficients of x and y are in same ratio in case of parallel line. But not the constant term. If constant terms are also in same ratio, both equations will become same i.e. will represent same line)
