Answer:
The coordinates of D(5,2)
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given point C(1,-4) and mid point M( 3,-1)
we have to use mid-point formula
<u><em>Step(ii):-</em></u>
Given mid point M( 3,-1) and (x₂ , y₂ ) be the 'D' co-ordinates
⇒ and
1 + x₂ = 3 ˣ 2 and -4 +y₂ = -2
⇒ x₂ = 6-1 =5 and y₂ = -2 +4
⇒ x₂ = 5 and y₂ = 2
<u><em>Final answer:-</em></u>
The coordinates of 'D' = (5,2)
