Question

draw the graph of the equation 4x-5y=20 and check whether the points( 3,1 )and( 5,0 )lie on the graph

Answer 1

only (5,0) lies on the line  

Answer 2

Answer:

Step-by-step explanation: first we will find the value of x and y as,

4x-5y=20

X=20+5y/4

You will find that

X=0,5,2.5

Y=-4,0,-2

Through this u can make a graph

Now to verify that

3,1 and 5,0 lie on graph,

You can put the value 3 and 5from both (3,1 and 5,0) and put in place of x in the above equation given in question.

Similarly the value of y= 1,0

If the equation appears equal than 3,1 and 5,0 Will definitely lie on graph.

Hope it will help.

Even now if u have any doubt u can ask ....
