Explain how to write a function rule from table below. then write function rule.

(x) 2, 4, 6

(y) 1, 0, -1

The linear equation describing the given table is y = (-1/2)x + 2.

Step-by-step explanation:

Let's assume that this is a linear function.

As we go from x = 2 to x = 4, (an increase of 2), y goes from 1 to 0 (a decrease of -1).  Thus, the slope of the line is m = rise / run = -1/2.

Borrowing info from the table:  when x = 4, y = 0.

Thus, y = mx + b becomes 0 = (-1/2)(4) + b, so that b = 2.

The linear equation describing the given table is y = (-1/2)x + 2.

answer: it's upside down and i can't read it

step-by-step explanation:

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)
