&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;&lt;u&gt;1. 
Find the slope of the line passing through the points(-8,-3) and (-2,2).&lt;/u&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&amp;nbsp;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;Slope = 
(Y&lt;sub&gt;2&lt;/sub&gt; - Y&lt;sub&gt;1&lt;/sub&gt;)/(X&lt;sub&gt;2&lt;/sub&gt; - X&lt;sub&gt;1&lt;/sub&gt;)&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;Just 
identify which coordinate corresponds to which in the slope formula, substitute 
them and you will have your slope.&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;&lt;u&gt;&lt;br&gt;
2. Which of the ordered pairs &lt;br&gt;
(3,1),(0,-4),(-4,0),(-3,-7) are solutions for the equation x-y=4?&lt;/u&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;You can 
rewrite x -y = 4 as&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;x = 4 + 
y&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;or&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;x - 4 = 
y&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;I&#39;ll go 
with x = 4 + y since it&#39;s easier to use. This equation states the value of 4 and 
the value of the y coordinate gives x. So we have to use guess and check here, 
but it&#39;s really quick to do. (3,1): Does 4 + 1 = 3?&amp;nbsp; (0,-4): Does 4 + -4 = 
0? Continue with this logic and you will have your answer(s). (There may be more 
than one answer.)&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;&lt;u&gt;&lt;br&gt;
3. An employee who produces x units per hour earns an hourly wage of 
y=0.35x+11(in dollars). What is the hourly wage of an employee who produces 2 
units per hour?&lt;br&gt;
&lt;/u&gt;&lt;br&gt;
X is the units per hour, and since you want to find out the hourly wage of an 
employee who produces 2 units per hour, just substitute 2 into the formula:&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;y = 
0.35(2) + 11 &lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;Y 
represents dollar so just solve for y.&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&amp;nbsp;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;&lt;u&gt;4. 
Graph x = 3&lt;/u&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;font face=&quot;Verdana&quot; size=&quot;2&quot;&gt;You 
know that if x = 3, this line must run through the point (3,0). Now all you need 
is the slope. However, is there slope here? If there isn&#39;t, what does that 
mean? &lt;/font&gt;&lt;/p&gt;
&lt;p style=&quot;margin-top: 0; margin-bottom: 0&quot;&gt;&lt;br&gt;
&amp;nbsp;&lt;/p&gt;

&lt;/body&gt;

&lt;/html&gt;
