Best ResponseYou've already chosen the best response.0im not sure how to get it, i got 4 for b , but how do i get m?

Best ResponseYou've already chosen the best response.0Solve the equation after you insert any point and 4 for b.

Best ResponseYou've already chosen the best response.0you can get m by subtracting y1 from y2 over x1 from x2

Best ResponseYou've already chosen the best response.0the slope of a horizontal line is 0... so the equation is: y = 0x +4 y = 4

Best ResponseYou've already chosen the best response.0ok that makes sense, so m=0

Best ResponseYou've already chosen the best response.0ok so how would i do this one, (5.1,2.3) and (3.5,3.7) . whats the first thing i should do?

Best ResponseYou've already chosen the best response.0first thing is to figure out the slope.. slope is defined by how steep the line rises. y1 y2 slope =  x1 x2

Best ResponseYou've already chosen the best response.06  is what I get if I added it right :) 8.6

Best ResponseYou've already chosen the best response.0we can reduse that to make it easier to see: 6/8.6 = 60/86 = 30/43

Best ResponseYou've already chosen the best response.0now stick that slope into your equation for the line: y = mx + b y = (30/43)x + b

Best ResponseYou've already chosen the best response.0pick any of the points they gave you and stick them in for x and y (x =3.5, y=3.7) 3.7 = (30/43)(3.5) + b now solve for b

Best ResponseYou've already chosen the best response.0m is the slope and b is the y intercept, i.e the point lying on y axis
