The answer for this question that needs an answer is n = 5
because 18(n-1) = 9(n+7) implies that 18n - 18 = 9n + 63 which implies that n =5 for the equation to hold true.
6 - 15/40 = 0.375 = 37.5%
When looking to convert a decimal to a percent you move the decimal over two places so, 0.375 becomes 37.5
8 - 70*1.2 = 80
You see 100% is equal to 1.00 when multiplying/dividing. So 1.2 = 120%
10 - 48*0.25 = 12 and 12+48 = 60 So, 60.
Here, we use 0.25 because 100% - 75% = 25% or... 1.0 - 0.75 = 0.25
Assuming you want the equation in slope intercept form, you first need to use slope formula to find the slope.

Plug in the coordinates that you have, (3,-1) and (4,7), for the x and y values respectively.

Which reduces to 8/1=8.
The slope of your equation is 8.
Slope intercept form is: y=mx+b. m is your slope and b is your y-intercept, x and y stay unchanged.
Plug the slope in:
y=8x+b.
Now, you can plug one of the sets of coordinates into the x and y of the equation to find b. I'm using (3,-1).
-1=8(3)+b
-1=24+b
Subtract 24 from both sides.
-25=b
Now plug this into the equation!
y=8x-25 is your final equation.
I hope this helps :)
