Use the following sets of information to answer this set of questions.

You are told that there are two linear lines in a coordinate graph with x the variable on the horizontal axis and y the variable on the vertical axis. The first line contains the points (5, 10) and (10, 20), while the second line contains the points (0,20) and (10,0). From this information find the equations for lines 1 and 2 and the solution for this set of equations.

You are told that there are two linear lines in a coordinate graph with x the variable on the horizontal axis and y the variable on the vertical axis. The first line has a slope of -1 and contains the point (100,100). The second line has a y-intercept of 20 and in addition, you know that every time the x variable increases by 10 units the y variable increases by 20 units. From this information find the equations for lines 1 and 2 and the solution for this set of equations.

You are told that there are two linear lines in a coordinate graph with x the variable on the horizontal axis and y the variable on the vertical axis. You are told that initially the two lines can be described by the two equations Y = 10 – X and Y = X. Then, you are told that at every y value the amount of the x variable has increased by 5 units for the first equation (Y = 10 – X). What is the initial solution for the original two equations? What is the new equation for the first line after the described change? What is the new solution for the revised set of equations?

You are told that there are two linear lines in a coordinate graph with x the variable on the horizontal axis and y the variable on the vertical axis. The first line is a vertical line where the value of x is always equal to 10 no matter what the value of y. The second line has a slope equal to -2. The solution for the two equations is given by (10,80). What are the equations for the two lines?
