 General rule for equation of Line is:
 
   Y = mX + b 
 
      You should have M1, and coordinate of one  point given , i.e. (X1,Y1), and m1
 
      Y =M1 + b  
     
         Plug in  (x1,Y1) in the equation
 
         b  = Y1 - M1X1
         back into equation
         
         Y = M1X - Y1 - M1X1
            In your example  m = 2  say it passes through point ( 2,3).
 
           Y = 2X + b
            3 = 2(2) +b
           b = 3-4 = -1
 
            Y = 2X -1 
  
      
Hi Crystal,
 
First, you need to find the equation of this line. Since you have the slope and a point (0,0) we can use the point-slope formula to get the equation of this line. 
 
Point-slope formula: y - y1 = m(x - x1)      m = 2, x1 = 0, and y1 = 0
                              y - 0 = 2(x - 0)
                              y =2x   ---> this is the equation of line
 
To find the other y-values to complete the table take the x values and plug them into the equation of the line y = 2x to get the y-values. So your final answer for your table will be:
 
x   0    1    2    3
y   0    2    4    6
 
I hope this helps. Please leave feedback. Thanks!
Hey Crystal -- slope "m" is "rise over run" ... m=2 means that when x runs 1, y rises 2 ... when x runs 2, y rises 4 ... x runs 3, y rises 6 ... Regards, ma'am :)
