Question

the 3 vertices of a parallelogram taken in order are (-1,0),(3,1)and (2,2).find the 4th vertex
​

Answer 1

Answer:

(0, -1)

Step-by-step explanation:

(2, 2), (3, 1)

slope m = (1 - 2) / (3 - 2) = - 1

Slopes of parallel lines are equal

point-slope equation of ║ line is through (-1, 0)

y - 0 = - 1 * (x - (-1))

y = - x - 1
