How to solve this problem step by step. make brainliest answer if its done.

D is halfway between A and B

so the coordinates of D are (2,2)

E is halfway between A and C so the coordinates of E are (-1,1)

now you need to find the gradient/slope of DE and BC using the formula:

SUB IN COORDINATES OF D AND E

therefore the gradient of DE is 1/3.

SUB IN COORDINATES OF B AND C

therefore the gradient of BC is -2/-6 which simplifies to 1/3.
