How to set up a system of equations

To set up your system of equations is to have 2 equations. They both would have 1 similar variable. For example, Jenny is 5 more her brother's age. She is also 2 more than twice her brother's age. You would set this up as Y, which is Jenny, and X, her brother. Y = 5 + x and Y = 2x + 2. Make sure you put Y in the same spot in both equations. Then take the other half of the equations and simplify them. 5 + x = 2x + 2. Subtract x from both sides to get 5 = x + 2. Subtract 2 from both sides to get 3 = x. Now replace the X from both equations to get Y = 5+3, and Y = 2(3) + 2. You will see both add up to 8, which is how old Jenny is in this example. Hope this helped!

The answer to your question is: letter C slope = -2; point (-8, 3)

Step-by-step explanation:

Point  slope of the line

                                       (y - y1) = m (x - x1)

                                       y - 3 = - 2(x + 8)

                                      slope = -2

                                     point = (-8 , 3)
