Hope this helped!
Answer:
The slope is 2
Explanation:
(2--6)/(2--2)=8/4=2
(y2-y1)/(x2-x1) the numbers besides the variables are subscripts.
Answer:
The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.
I don't think I put enough detail into that explanation but I hope this helps your problem.
