Answer:
Which ones you need help with? All of it?
Step-by-step explanation:
0.4÷0.515=0.8 rounded to the nearest tenth.
First graph your x and y intercept then pick any two points on the line.

that's the equation used to find your slope
Example:
(4,2) (8,6) let's say those are the points you pick from the line
so then you subtract 6-2=4 (6 is your y2 and 2 is your y1)
then subtracts 8-4=4 (8is your x2 and 4 is your x1)
then your left with

if you can reduce the reduce in this case you can which leaves you with

and that's how you find the slope
Answer:
7 points
Step-by-step explanation:
started out w/ 5 points, then loses 8
5 - 8 = -3
gains 10 points
-3 + 10 = 7
