If you graph the end points C and D then graph the 4 points at the end it is difficult to tell which points are on CD without a line.
Using the endpoints find the slope (change in y/ change in x) then substitute a point in to find the intercept.
Slope = (-6-4)/(6- -8) = -5/7
Intercept equation (-6) = -5/7 (6) + b
b = -1.71428571429
Graphing the line shows only 2 points on the line (–2.75, 0.25) and <span>(0.75, –2.25)
I am confused by the part, "</span><span>P is the length of the line segment from D". Were you given a length P to help you determine which point. Using the distance formula to find the length from each point to D doesn't help determine which one is best with the information you have given. The image shows the distances I calculated and the graphed points.

Reason number 1 (before) is that you could contaminate your samples if you have foreign material on your hands.
Reason number 2 (after) is that you could spread<span>/or ingest dangerous chemicals or substances that you have handled in the lab.</span>

Answer:
6*10^-6
Step-by-step explanation:
You need a whole number for the scientific notion, right? To find that number above 1 and under 10, you can move the decimal point over until you get that number. Count the amount of spaces you moved the decimal point, and that's your number for scientific notation. To get the negative sign, you have to determine whether for scientific notation you make your number bigger or smaller. If you make it bigger, you have to put a negative sign on the exponent. If the number becomes smaller, it is a positive number. Hope this helps!
