Answer:

y = -1x - 79

Step-by-step explanation:

Formula is y = mx + b

m is slope

slope = change in y / change in x = (-23 - -15) / (-56 - -64) = -8/8 = -1

m = -1 so equation is now y = -x + b

Now to find b, substitute any coordinate from the table in the equation. Let's use (-64, -15).

y = -x + b

-15 = -(-64) + b

-15 = 64 + b

-79 = b

So the equation is y = -1x - 79
