Best ResponseYou've already chosen the best response.0The first thing you need to do is figure out the slope of the line. To do this, use the equation: \[m = (y _{2}y _{1})\div(x _{2}x _{1})\] Then, substitute either of your points, and your previously calculated slope, into the equation

Best ResponseYou've already chosen the best response.0Whoops, sorry... Into the equation \[yy _{0}=m(xx _{0})\] and solve for y. \[(x _{0},y _{0})\] You have to calculate the slope. Use the equation I gave you before to solve for m (slope). Use your point (5,4) as (x1,y1) and (3,1) as (x2,y2).

Best ResponseYou've already chosen the best response.0(5,4) and (3,1) M=(Y1Y0)/(X1X0) M= [1(4)]/[3(5)] M= (1+4)/(3+5) M=3/2 THEN WE KNOW THAT Y=MX+B USING ONE OF THE POINTS (3,1) 1=3/2 (3) + B 1 = 9/2 +B 1+9/2 = B 7/2 = B THEREFORE THE EQUATION WILL BE: Y= MX+B Y=(3/2)X + 7/2 =)
