Solve the system by graphing.
{y=−7/4x−1 (7 over 4x)
{-x+2y=16
(Please comment where I can label the points on what number on either x line or y line thank you correct answer gets brainliest)

Hi There the correct answer is {x,y} = {-1,-10}  

System of Linear Equations entered :

  [1]    3x - y = 7

  [2]    4x - 2y = 16

Graphic Representation of the Equations :

   y + 3x = 7        -2y + 4x = 16  

Solve by Substitution :

// Solve equation [1] for the variable  y  

 [1]    y = 3x - 7

// Plug this in for variable  y  in equation [2]

  [2]    4x - 2•(3x-7) = 16

  [2]    -2x = 2

// Solve equation [2] for the variable  x  

  [2]    2x = - 2  

  [2]    x = - 1  

// By now we know this much :

   x = -1

   y = 3x-7

// Use the  x  value to solve for  y  

   y = 3(-1)-7 = -10  

Solution :

{x,y} = {-1,-10}  

Hope it helps!
