Me on how to solve this question, it is really confusing,
first one will get a brainliest answer and five gold stars.

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:

y2 - y1 ÷ x2 - x1

Gradient of DE:

SUB IN COORDINATES OF D AND E

1-2 ÷ -1-2

therefore the gradient of DE is 1/3.

Gradient of BC:

SUB IN COORDINATES OF B AND C

- 2 - 0 ÷ - 3 - 3

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

therefore, BC and DE are parallel as they both have a gradient/slope of 1/3 and parallel lines have the same gradient

answer

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
