Step-by-step explanation:
2×9n=18n
2×-6=-12
52-12+18n= 38 +18n
2×7n=14n
8×2=16
14n+16
38+18n=14n+16
subtract 14n from 14n and 18n
38+4n=16
subtract 38 from 38 and 16
4n=-22
divide each side by 4
n= -5.5
27 / 6588 = 0.00409836065
9+8 is the commutative property
To find the slope you do y1-y2/x1-x2
To find the y intercept you look at when x is zero what is y.
Equation is y=-1/2x -2
