Answer:
NOT a solution
Step-by-step explanation:
Substitute the values of x and y and see if the equation is satisfied:
3(1) -7(-1) = 3 +7 = 10 ≠ 4 . . . . . . the given point is not on the line
(1, -1) is not a solution to the equation.
_____
(-1, 1) is a solution
The answer is A.Use a compound interest calculator. Multiple sites to use. For me, I had to use my head for a while

Write an equation to present her daily earnings?
Let daily sales be represented by x and daily earnings be represented by y.
y is calculated as thus;
![y = Earnings + Commission * Sales](https://tex.z-dn.net/?f=y%20%3D%20Earnings%20%2B%20Commission%20%2A%20Sales)
![y = 30 + 2\% * x](https://tex.z-dn.net/?f=y%20%3D%2030%20%2B%202%5C%25%20%2A%20x)
Convert percentage to decimal
![y = 30 + 0.02 * x](https://tex.z-dn.net/?f=y%20%3D%2030%20%2B%200.02%20%2A%20x)
![y = 30 + 0.02x](https://tex.z-dn.net/?f=y%20%3D%2030%20%2B%200.02x)
Hence, her daily earnings is ![y = 30 + 0.02x](https://tex.z-dn.net/?f=y%20%3D%2030%20%2B%200.02x)
