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.

Answer:
1) increases
2) decrease
3) increase
4) decrease
Explanation:
When ionic compounds dissolve in water, the concentration of ions in solution increases since ionic substances dissociate into ions in solution. The greater the concentration of ions in a solution, the greater the ionic strength of that solution.
Hence, if HNO3 is added to KOH solution, the ionic strength of the solution is increased due to an increase in the number of ions in the solution.
Also, when benzoic acid is titrated against KOH, potassium benzoate (an ionic substance) is formed thereby increasing the ionic strength of the solution.
However, when KOH is added to CaCl2, a precipitate (Ca(OH)2) is formed. Also, when NaOH is added to FeCl2, a precipitate (Fe(OH)2) is formed. In both cases, the formation of the precipitate decreases the concentration of ions in the solution thereby decreasing the ionic strength of the solution.
Answer:
b.) 25 ml of aluminum hydroxide
Explanation:
For this question, we have to assume that we have the <u>same concentration</u> for all the solutions, for example, <u>1 M</u>. Additionally, we have to take into account the <u>ionization reaction</u> for each species:
a) 
<u>we have to ions</u>
b) 
<u>we have fourth ions</u>
c) 
<u>we have two ions</u>
d) 
<u>we have one ion</u>
If we have the same volume and the same concentration the variables that will help us to answer the question would be the n<u>umber of ions.</u> If we have <u>more ions we will have more particles dissolved</u>. Therefore the answer would be b) (<u>due to the fourth ions</u>).
I hope it helps
I think the land for it represents a DUNE
