Find coordinates for x+5y=10 and 3x+5y=0. I need to know how to do this plz explain.
maks197457 [2]

Answer:

(-5,3)

Step-by-step explanation:

<em><u>Method</u></em>

There are several ways you can do this, but one of the best ways is to use a graphing coordinate calendar. The most popular one is Desmos Graphing Calculator. I've attached an image of my work below using the system.

<u><em>Answer</em></u>

As you can see, both equations intersect at a certain coordinate point. This coordinate point is the point you need for the answer. The intersection is (-5,3).

I hope this helps. If you have any more questions, please feel free to post them and someone will be able to help you, whether it's myself or others. Please leave a like, rating, and if possible, Brainliest. Have a great day!
