Help: Pictures are below: match the equations to the lines below:

__ y = 2x - 1 1) A
__ y = 1/2x - 1 2) B
__ y = -1/2x + 1 3) C
__ y = 1/2 x + 1 4) D
__ y = -2x - 1 5) E
__y = -1/2x + 1 6 ) F

If a(0,0,0) and b(2,2,2) are points in coordinate space, how many paths are there from a to b that move from one lattice point to another in the positive x-,y- or z- direction?

()1. how do you find range? 2.the following set of data is to be organized into a histogram. if there are to be five intervals on the graph, what should the length of each interval be? 30, 34, 23, 21, 27, 25, 29, 29, 25, 23, 32, 31

Is this a polynomial function? i need to know asap
