Question

i) Co-ordinate of point J is -2 and co-ordinate of point A is 1 then find d(J, A)​

Answer 1

Answer:

It is known that, between the two points is btained by subtracting the smaller co-ordinate from larger co ordinate.

(i) The co-ordinates of points B and E are 2 and 5 respectively. We know that 5 > 2.

d(B, E) = 5 - 2 = 3

(ii) The co-ordinates of points J and A are -2 and 1 respectively. We know that 1> -2. d(J, A) = 1(-2)=1+2=3

(iii) The co-ordinates of points P and C are -4 and 3 respectively. We know that 3> -4.

d(P, C)=3-(-4)=3+4=7

(iv) The co-ordinates of points J and H are -2 and -1 respectively. We know that -1 > -2.

d(J, H) = -1 - (-2) = -1 + 2 = 1

(v) The co-ordinates of points K and O are -3 and 0 respectively. We know that 0> -3. d(K, O) = 0 - (-3) = 0 + 3 = 3

(vi) The co-ordinates of points O and E are 0 and 5 respectively. We know that 5 > 0.

d(0, E) = 5 - 0 = 5

(vii) The co-ordinates of points P and J are -4 and -2 respectively. We know that -2 > -4. d(P, J) = -2- (-4)= -2+4= 2

(viii) The co-ordinates of points Q and B are -5 and 2 respectively. We know that 2 > -5.

d(Q, B) = 2 (-5) = 2+5=7
