<u><em>Answer:</em></u>
<em>You haven't attached a picture but this is what your line should look like </em>
<em> </em>
<em>Step-by-step explanation: </em>
<em> </em>
<em>For this equation you simply have to graph it. </em>
<em> </em>
<em>First, you have to remember that these equations follow a formula: y=mx+b. m is the slope of you line and b is the y-intercept. </em>
<em> </em>
<em>Next, you need to graph it. First, graph your b, in this case 2. You would go up 2 on you graph (graph (0,2)). Then, you would graph your slope which is 3. </em>
<em> </em>
<em>Now, remember that slope equals y/x, so think of the number 3 being like 3/1. You would start at (0,2) and go up 3 points in the graph, then over 1 point (graph where you end up). You repeat that from each new point you make until you have enough points to create a straight line. </em>

Answer:
Mean=50.
standard deviation=50.
Step-by-step explanation:
Let the perfect score be 100.
The mean(average) of a data is given by:
Here the number of data points are 100. out of which 50 attains a value 100,and 50 attains value 0.
so, sum of data points=50×100+50×0=5000.
Mean=50.
"Now the standard deviation of data points are calculated by firstly subtracting mean from every entry and then square the number and take it as new entry and calculate the mean of the new data entry and lastly taking the square root of this new mean".
Here if 50 is subtracted from each entry the new entry will have 50 entries as '50' and 50 entries as '-50'.
next on squaring we will have all the 100 entries as '2500'.
now the mean of these entries is:
=2500
taking it's squareroot we have
Hence, standard deviation=50.
