| Question 1203163:  The straight line y=mx+c passes through the points (0, k) and (h,2k)
 Express m and c in terms of h and k
 What I have tried
 A.         B.
 .........................
 (0,k)     (h, 2k)
 (X1,Y1).   (X2, Y2)
 M= (Y2-Y1)/(X2-X1)
 M= k/h
 Y-Y1=m(X-X1)
 ====
 Y=kx/h +K
 C=K

You can put this solution on YOUR website! The straight line y=mx+c passes through the points (0, k) and (h,2k) Express m and c in terms of h and k

 Y=kx/h +K

 ===============================
 Slope m = (2k-k)/(h-0) = k/h
 ---------------
 (0,k) is the y-intercept, so c = k

You can put this solution on YOUR website! The two points  (0,k) and (h, 2k); 
 Directly to formula of slope,
 
   
 
   
   
 Also using slope intercept form,
  and now having an expression found for slope m, picking your first given point  (0,k),
 
  , which you could have jumpted through much more quickly; 
  
   
 
 Understand, first given point (0,k) indicates that vertical axis intercept is k.
 You would not really need to SOLVE for c.
