The y is the same for both equations. Equate them -x - 5 = 2x + 4 Add x to both sides - 5 = 3x + 4 Subtract 4 from both sides. - 9 = 3x Divide by 3 x = -9 / 3 x = - 3
y = - x - 5 y = -(-3) - 5 y = - 2
So that point is where the two equations meet.
To see the graph of your question on the internet, go to Wolframalpha.com and put this string in the question space. y = -x - 5; y = 2x + 4 Note the semi colon in the middle.
To the moderator: This is my own work. I'm using Wolfram to get the answer.
