Best ResponseYou've already chosen the best response.1First we need to find the slope

Best ResponseYou've already chosen the best response.1Or in other words just 1 what form do they want the equation in?

Best ResponseYou've already chosen the best response.1oh ok so now we use the point slope equation \[\huge~\rm~yy_1=m(xx_1)\] (x1,y1)=(3,2) m=slope which is 1 just plug in the given information and solve for y

Best ResponseYou've already chosen the best response.0or you can use y = mx + b...either formula will work

Best ResponseYou've already chosen the best response.1x and y are just there they help to figure out the slope and the equation

Best ResponseYou've already chosen the best response.0and you x and y points.....you can use either set (3,2) or (2,3)

Best ResponseYou've already chosen the best response.0which formula do you want to proceed with ?

Best ResponseYou've already chosen the best response.0you forgot about your slope(m) of 1

Best ResponseYou've already chosen the best response.0y = mx + b slope(m) = 1 (3,2)...x = 3 and y = 2 now we sub 2 = 1(3) + b 2 = 3 + b  add 3 to both sides 2 + 3 = b 5 = b so your line is : y = 1x + 5 or just y = x + 5 but if you sub in your other set of points..(2,3) 3 = 1(2) + b 3 = 2 + b 3 + 2 = b 5 = b same thing....y = x + 5 so either of your points will give you this answer

Best ResponseYou've already chosen the best response.0now if they wanted the answer is pointslope form you would use : y  y1 = m(x  x1). You could also use it for this problem but you would eventually have to change it to y = mx + b form
