The graph is a straight line with this characteristics:
slope: the coefficient that accompanies the x variable, so it is 2.
x-axis intercept: find from y = 0 => 2x - 6 = 0 => x = 3
y - axis intercept: find from x = 0 => y = 2(0) - 6 = 6.
With that information you can draw you graph.
Just in case you need more information, you can build a table with several values of x and y:
x y = 2x - 6
-5 2(-5) - 6 = -16
-4 2(-4) - 6 = -14
-3 2(-3) - 6 = -12
-2 2(-2) - 6 = -10
-1 2(-1) - 6 = -8
0 2(0) - 6 = -6
1 2(1) - 6 = -4
2 -2
3 0
4 2
5 4
Now you have plenty information to draw the graph.
6 6
Cylinder are used to measure those things so yes correct I can’t write it all sorry
Answer:
earthquakes yeah i'm pretty sure -
Explanation:
Answer: 
Explanation:
Given
Mass of iron piece is 
Heat absorbed 
Temperature changes from 
i.e.
Heat absorbed is given by ![Q=mc\Delta T\quad [c=\text{specific heat of material}]](https://tex.z-dn.net/?f=Q%3Dmc%5CDelta%20T%5Cquad%20%5Bc%3D%5Ctext%7Bspecific%20heat%20of%20material%7D%5D)
Insert the values
Thus, the specific heat of iron is
