Hello,
I have a graphing calculator so this will be easy for me to answer and explain how to figure these out. Here we go!
1. Well on a Ti - 84 plus calculator it says graph then you put in thee equations for each and C and D are already incorrect cause they go straight up and B is incorrect because it is a straight line on the top going straight. In this case your looking for a line that goes through the dots. And the answer would be A) Y = 1/2x + 7.
2. B) Then umber of accidents were reduced by 0.67 per month for every additional driver in the program.
3. Key: Y means yes N means no. Plot A had 1 disease present and 2 not present. Plot B has 3 diseases present and 1 disease not present.
4. Category A had 36 groups in group 1. and Category B had 12 groups in group 1. Easy!

Hope I Helped!
Have a fantastic Day!
Answer:
Equation of the line: 
.
Step-by-step explanation:
Let 
and 
denote the coordinates of these two points, respectively.
Calculate the slope 
of this line:
.
Notice that the slope is zero because the two points have the same 
-coordinates (
) even though their 
-coordinates are distinct (
.)
Equation for this line in point-slope form:
.
.
Rewrite and simplify to obtain the equation of this line in slope-intercept form:
.
The -term was eliminated because the slope was zero.
<h2><em>The last graph because the slope is 40.
</em></h2><h2><em>
</em></h2><h2><em>Slope equals rise over run
</em></h2><h2><em>
</em></h2><h2><em>Rise is 4/ Run is 1
</em></h2><h2><em>
</em></h2><h2><em>4/1=4
</em></h2><h2><em>
</em></h2><h2><em>Slope (rate of change)=4</em></h2><h2><u><em>C</em></u></h2>
