Question
An equation of the graph shown is ax + by = 6, where a & b are constants. What is the value of b?

- -3
- -1
- 1
- 3
The correct answer is: -3
We substitute the coordinates of a point on the given line ax + by = 6 from the given graph and find the value of b.
Step-by-step solution:-
Point B (0,-2) lie on the line as per the given diagram.
Substituting this point in equation- ax + by = 6, we get-
a (0) + b (-2) = 6
∴ 0 - 2b = 6
∴ -2b = 6

Final Answer:-
Option A i.e. -3 is the correct Option.

A sports store had 60 backpacks in store, some with wheels and some without wheels, before a new shipment of backpacks arrived The number of wheeled backpacks in the new shipment was twice the number of wheeled backpacks already in stock, and the number of backpacks without wheels in the new shipment was 5 times the number of backpacks without wheels already in stock. After the new shipment arrived, there were 330 backpacks in the store. Before the shipment there were x wheeled backpacks and y backpacks without wheels. Which of the following equations can be used with x + y = 60 to solve for x & y?
