Ineed asap graph the system of equations 2x+y=5; 14+7y=35

To do the first one, we need to find two points where the coordinates are integers (just for simplicity). First, notice that when x = 0, y is 5, and when x = 1, y = 3. So, graph the points (0, 5) and (1, 3) on the coordinate plane and connect them with a line.

For the second one, I assume you meant to put 14x + 7y = 35. So, to simplify things, let's divide  both sides by 7 to get 2x + y = 5. This is the same one! So, we can go back to out previous answer.

If it wasn't 14x + 7y = 35, I will post the graph to 14 + 7y = 35. Divide both sides by 7 to get 2 + y = 5, or y = 3. So, take two points where x is any number and y is 3, and connect these.

You have to put it in Y=MX+B form, so that mean you subtract the 2x in the first equation and move it to the other side of the equal sign so it will look like this Y=2X+5 and for the second equation you do the same thing and thats your answer

Obtuse...

set up pythagorean theorem

you should get
784=225+529
784>754 which makes it an obtuse triangle
