Question

3. Write the pairs of coordinates satisfying y = 5x. Do the values of y make a table of 5. draw the
graph and from the graph read the value of 5 x 7 and 5 x 8.​

Answer 1

Pairs of coordinates satisfying y=5x are (0,0),(1,5),(2,10),(3,15),(4,20),(5,25) etc

The value of 5 times 7 is 35 and of 5 times 8 is 40

-clearly the y coordinate follows table of 5 i.e., 5,10,15,20,25 and so on..

-From the graph shown, since we know that the y coordinate follows table of 5, to find 5 times 7, we look at x=7 and corresponding y value i.e., 35 gives the answer

-similarly to find 5 times 8, look at x=8 and corresponding y value i.e., 40, gives the answer
