can somebody please tell me the equation for this table? (Sorry it isn’t an actual picture, it wouldn’t let me upload my picture.)
+128473 Notice that as y changes by +1, x changes by -2
So....this is a linear equation where the slope, m, =
change in y / change in x =
+1 / -2 = -1/2
So.....using y = m ( x - x1) + y1 where (x1, y1) is any point on the graph, we have
y = (-1/2) ( x - 4) + 0 simplify
y = (-1/2)x + 2
