Question

C(4,-5) is a given point. If the coordinates of D are _ then CD is parallel to the y axis.​

Answer 1

Answer:

Step-by-step explanation:

(i) (2, 3), (4, 1) (ii) (–5, 7), (–1, 3) (iii) (a, b), (–a, –b)Sol. (i) Here x1 = 2, y1 = 3, x2 = 4 and y2 = 1         ∴ The required distance          

Q.2.   Find the distance between the point (0, 0) and (36, 15). Can you now find the distance between the two towns A and B discussed in Section 7.2 of the NCERT textbook?Sol. Part-I         Let the points be P(0, 0) and Q(36, 15)

Answer 2

Answer:

Constant

ii) Constant

iii)y=k⟹0x+y=k

iv)x=k⟹x+0y=k
