I don't exactly know what you're asking but I can give you this:
Aiden paid 22.2 $ in total
His sister paid 8.5$ in total
He paid 13.7 $ more than his sister
-8 + -7 + -5 + -3 + 3 + 5 + 7 + 8

your answer is 0!
Y = mx + b is the slope-intercept form of the equation of a line,
where m = slope, and b = y-intercept.
In problems 1 and 3, your equations are written in the y= mx + b form, so you can read the slope and y-intercept directly.
1.
m = -5/2
b = -5
3.
m = -1
b = 3
5.
For problem 5, you need to solve for y to put the equation
in y = mx + b form. Then you can read m and b just like we did
for problems 1 and 3.
4x + 16y = 8
16y = -4x + 8
y = -4/16 x - 8/16
y = -1/4 x - 1/2
m = -1/4
b = -1/2
2.2 i think because 12 divided by 5 2/5 = 12 divided by 5/27 = 2.2
