Best ResponseYou've already chosen the best response.3rate of change means slope :) So you want to find the slope for each of the functions.

Best ResponseYou've already chosen the best response.3you're welcome :) Well can you tell me what you got as the slope for each of the functions?

Best ResponseYou've already chosen the best response.1rearrange the functions to the form y = mx + b m will be your slope

Best ResponseYou've already chosen the best response.1B is in that form already y = 6x  5 so its slope = 6

Best ResponseYou've already chosen the best response.1well rearrange A to y = mx + b form

Best ResponseYou've already chosen the best response.1yes now for C you need to see how y increases with unit increase of x as x goes from 2 to 1 y does from 7 to 2 so thats a slope of ?

Best ResponseYou've already chosen the best response.3you might want to use the slope formula: m (slope) = rise/ run \[m = \frac{ y2  y1 }{ x2  x1 }\]

Best ResponseYou've already chosen the best response.1yes that will give you the slope from the points on the graph

Best ResponseYou've already chosen the best response.1you can use that for option D

Best ResponseYou've already chosen the best response.1for option C the slope is 2(7) / 1(2)

Best ResponseYou've already chosen the best response.1how mant units is it from 7 up to 2 ?

Best ResponseYou've already chosen the best response.1right and 2 to 1 is one unit slope = 5/1

Best ResponseYou've already chosen the best response.1now to find the slope for D plug in the points (1,3) and (0,2) into (x2,y2) and (x1,y1) into the formula for m that butterfly dreamer posted
