Me answer this question i will give

I think it's y=-1/2x+8

Because if you use two and seven for example you could substitute the x and have:

y=-1/2(2)+8

y=-1+8

y=7

which proves the equation correct

So the answer is y=-1/2x+8

step-by-step explanation:

in which figure is point g a centroid

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
