Best ResponseYou've already chosen the best response.0The change is 10 because everytime x increases by 2 y increases by 10 and so on.

Best ResponseYou've already chosen the best response.0Find the rate of change for each table, equation, or graph. How did you find the rate of change?

Best ResponseYou've already chosen the best response.1rate of change has the same meaning as slope of a line or gradient, denoted by m slope = change in y / change in x or if we have two points (x1,y1) and (x2,y2) then the rate of change is \[m=\frac{ y _{2}y _{1} }{ x _{2}x _{1} }\]

Best ResponseYou've already chosen the best response.1for your first problem, consider that you have three points we can use any two points, I'll use the first two points (2,10) and (4,20) so we have x1 = 2, y1 = 10, x2=4, and y2=20 now, can you calculate the rate of change using the formula above? :)

Best ResponseYou've already chosen the best response.1a point in Cartesian coordinates is stated as (x,y) , the horizontal line is xaxis and the vertical line is yaxis, so the first point is (6,25) and the second one is (0,0) Now, what is the rate of change of the line? (use the previous formula)

Best ResponseYou've already chosen the best response.0Write an equation in slopeintercept form, pointslope, or standard form for the line with the given information. Explain why you chose the form you used. a. Passes through (1, 4) and (5, 2) We will just start with A lol
