What is the slope of the line that contains these points?

x 39 40 41 42
y 36 29 22 15

slope:

Neither is the answer

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0 

The answer to your question is 25hope this !
