Question

Use the graph below and answer the following questions. a) Explain what the C-intercept means in real-life according to the graph? (1 mark) b) How much would it cost to buy 3 bags of rice? c) How many bags of rice can you get with $20.00? d) How much would it cost to buy 10 bags of rice? Justify your calculations

Answer 1

Step-by-step explanation:

Slope=31.5 ........................

Answer 2

Firstly, if you calculate the slope y2-y1/x2-x2

It will be 5. This tells us that for every 1 unit we move along x axis, 5 units will increase in y axis.

Y-intercept (c) means where the graph meets the y axis in this case it's the origin.

By graph you can see 3 bags of rice will cost 15 dollars.

Also that by 20 dollars you can buy 4 bags of rice.

Now for 10 bags of rice means we move ten units on the x axis. Since we know that for every unit in x axis we move 5 units in y axis. Therefore price of 10 rice bags will be 10*5 which is 50 dollars
