Use the graph below to answer the following question.
1 answer:
Answer:
is least soluble at high temperatures.
Step-by-step explanation:
The compound that has least solubility when the temperature increases is the one that has the least value along y-axis <em>(solubility)</em> for greater values along x- axis <em>(temperature).</em>
From the graph we see that is most soluble at high temperatures <em>(in fact its solubility increases with increase in temperature)</em>, and
is least soluble for high temperatures <em>(its solubility decreases with increase in temperature) .</em>
Thus,<em> </em> is least soluble at high temperatures.

Answer:
The answer is below
Step-by-step explanation:
The slope of a line (m) is given by:
Two lines are parallel if they have the same slope and perpendicular if the product of their slope is -1.
1)
Since the product of their slope is -1, they are perpendicular
2)
Since the slope is not the same or product of their slope is not -1, they are neither parallel or perpendicular
3)
Since the slopes are the same, they are parallel
4)
Since the slopes are the same, they are parallel
5)
Since the product of their slope is -1, they are perpendicular
