Plz help im failing plz

D) slope of function A is -2, function B is 4

Step-by-step explanation:

you can see from the equation, y=-2x+1, that the slope (or rate of change) is -2 because it is the coefficient of the 'x' term

to get the slope of Function B we can use the slope formula:

slope =

using points (1,1) and (3,9) we get:

slope = (9-1)/(3-1)

         = 8/2 or 4

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

good luck!
