Question

If the points (-6,5), (-2,2), and (10,y) are collinear, how would you solve for y using proportions?

Answer 1

Step-by-step explanation:

use triangle formula

1/2 (-6 (2-y)-2 (y-8)+10 (5-2))=0

-12+6y-2y+16+50-20=0

4y=-34

y=-8.5

Answer 2

Answer:

you can use area of triangle formula or distance formula to prove that these points are collinear
