Find two points on the graph that the line crosses through almost perfectly. It looks like (1,10) and (9,1) will do.
Use them to compute the slope:
m = (1 - 10) / (9 - 1)
= -9/8
Then set up the "point-slope form":
y - y0 = m * (x - x0)
You choose some point (x0, y0) that the line crosses through. We already know the line passes through (1,10) pretty well, so let's use that.
x0 = 1
y0 = 10
Now finish plugging into the equation:
y - 10 = -9/8 * (x - 1)
The above equation will work fine for an answer, but let's go a step further and solve for y.
y - 10 = -9/8x + 9/8
y = -9/8x + 9/8 + 10
y = -9/8x + 9/8 + 80/8
y = -9/8x + (9 + 80)/8
y = -9/8x + 89/8
So I think the rule is that you divide two exponents with the same base, you keep the base and subtract the powers.

yes they are the same

i dont know sorry
The answer for this would be NO. You can no longer reduce 9/10 since there is no factor that is similar between the two numbers. There is no other number that can also divide these numbers evenly except for 1. Therefore,it is already fixed and in the simplest form. Hope this answer helps.
