Answer this question fast and i will give you brainlest

1.the graph shows two lines, m and n.

how many solutions are there for the pair of equations for lines m and n? explain your answer.

2.consider the following pair of equations:

y = x + 4

y = −2x − 2

explain how you will solve the pair of equations by substitution. show all the steps and write the solution in (x, y) form.

the graph is for question 1.

{y,x} = {-6,-2}

Step-by-step explanation:

/ Solve equation [2] for the variable  y  

 [2]    y = 2x - 2

// Plug this in for variable  y  in equation [1]

  [1]    (2x-2) - x = -4

  [1]    x = -2

// Solve equation [1] for the variable  x  

  [1]    x = - 2

// By now we know this much :

   y = 2x-2

   x = -2

// Use the  x  value to solve for  y  

   y = 2(-2)-2 = -6
