Answer:
[0, 10]
Step-by-step explanation:
Plug the coordinates into the Slope-Intercept Formula. It does not matter which ordered pair you choose:
20 = 2[5] + b
10
10 = b
y = 2x + 10
__________________________________________________________
16 = 2[3] + b
6
10 = b
y = 2x + 10
** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

Answer:
There are 14 pairs of Brand A sold.
Step-by-step explanation:
In order to find this, you need to set up a system of equations. You can set up on equation for the number sold:
A + B = 32
And you can set up one for the amount made:
30A + 35B = 1090
Now, in order to solve for the amount of A sold, multiply the first equation by -35 and add the two equations together.
-35A - 35B = -1120
30A + 35B = 1050
----------------------------
-5A = -70
A = 14
