Math Question: y=-5 y=3x-2 Part A: Graph the system of linear equations. Part B: Use the graph created in Part A to determine the solution to the system. Part C: Algebraically verify the solution from Part B.

Part A: To graph the first equation, it will be a horizontal line where y is -5. The second line has a y-intercept of -2. It will have a slope of 3. So you go up 3 and to the right 1. Make sure you either have graph paper for this or make it on your own. Part B: The solution to the system of equations is going to be where these lines will cross. That point will be (-1,-5) Part C: To solve algebraically, you need to use substitution. This one is fortunately easy, as you already know the y-value. Plug -5 in for y in the second equation. Add 2 to both sides to eliminate the -2. You will get -3=3x. To solve that, divide 3 on both sides and you will get x=-1. So now you have the same solution as part B. X is -1 and y is -5 so the ordered pair is (-1,-5)
