Question

Identify the coordinates of the midpoint of JW¯¯¯¯¯¯, which has endpoints J(−1,−9) and W(7,−7).

Answer 1

`\large \bf \longrightarrow{(3, - 8)}`

Explanation:

Step 1) : Write the midpoint formula

`\large \implies \bf((x_1 + x_2)/(2), (y_1 + y_2)/(2) )`

Step 2) : Substitute (-1 , -9) and (7 , -7) into
`\bf((x_1 + x_2)/(2), (y_1 + y_2)/(2) )`

`\large \implies \bf(( - 1 + 7)/(2), ( - 9 - 7)/(2) )`

Step 3) : Calculate

`\large \implies \bf((6)/(2), ( - 16)/(2) )`

Step 4) : Cross out the common factor

`{\large \implies \bf(\frac{ \cancel{6}}{ \cancel{2}}3, \frac{ \cancel{ - 16}}{ \cancel{2}}} \bf - 8)`

Step 5) : We have got the answer

`\large \bf \implies{(3, - 8)}`
