Best ResponseYou've already chosen the best response.0Okay so it's telling me to see which answer choice has equations that are the same as the lines on the graph. So in order for me to find that I would have to graph each equation from the answer choice.

Best ResponseYou've already chosen the best response.0Let's start with A. The equations are \[x+2y=10\]and\[3xy=12\]First solve for y. In order to solve for y you would have to move all of the numbers and x over to the other side of the equal's sign. For example:\[x+2y=10\](Let's get rid of the x and move it to the other side) dw:1438811302574:dw Then you have to divide by 2 to get rid of the 2 next to the y. dw:1438811397930:dw

Best ResponseYou've already chosen the best response.0Okay you're close but that's not right. If you know how to solve for y from each equation you can just graph those equations into you're graphing calculator to see if the lines match the graph given.

Best ResponseYou've already chosen the best response.0Okay so you see the first equation in letter A?\[x+2y=10\]First step is to get rid of the variables/numbers that add or subtract with y. Did you understand that part?

Best ResponseYou've already chosen the best response.0Because x2y=10 makes the line go upwards from left to right. The line goes down from left to right in the picture.

Best ResponseYou've already chosen the best response.0Go to the website called Desmos. There you can launch a graphing calculator that can graph any equations. Even equations like these. So go to the website and type in your equations that way you can match the lines.
