Best ResponseYou've already chosen the best response.3\(\large (x_{1}, y_{1}) \) and \(\large (x_{2}, y_{2}) \) Match the coordinates with the formula \(\large (2, 8) ~~ (6, 12) \)

Best ResponseYou've already chosen the best response.3the two point s oyu have are (x1,y1) and (x2,y2) in this case x1=2 y1=8 x2=6 y2=12 put those numbers into the formula that @Luigi0210 gave you m is the answer for the slope...

Best ResponseYou've already chosen the best response.3@ibacon BEWARE!! You have got the answer right in this case BUT you got the equation wrong You have the equation upside down (it is only correct here because it was 4/4) BE CAREFUL on other questions

Best ResponseYou've already chosen the best response.0What is the slope of the line that passes through the points (1, 7) and (–4, –8)? A. –3 B. Slope C. Irrational Numbers D. 3 so what is the x1 x2 y1 y2 and the equation? @Luigi0210 @MrNood

Best ResponseYou've already chosen the best response.3you are given the 2 pairs of points you probably know they are in the order (x,y) in the brackets It doesn't matter which one you choose as 1 or 2 as long as you are consistent with the formula try it yourself the same as the last one

Best ResponseYou've already chosen the best response.3no sorry that is very wrong (x1,y1) = (1,7) (x2,y2) = (4,8) be careful with the signs when oyu do the subtraction

Best ResponseYou've already chosen the best response.3OK  now th eDEFINITION of the slope is the (change in y)  (change in x) and that is shown in the drawing:dw:1432835978112:dw do you follow that?
