 Hi and how are you all today? I'm Kanekha and let us do the following question. It says, draw the graph of each of the following linear equations in two variables. The first parts equation given to us is x plus y is equal to 4, right? So let us proceed on with our solution. Now here the equation given to us is x plus y is equal to 4 and we need to draw a graph. To draw the graph, first of all, we need to find few points. We'll get it by first putting the value of x as 0 and then putting the value of y as 0 in the above equation. The equation is x plus y is equal to 4. So on putting y is equal to 0, we have 0 plus y is equal to 4. That means y is equal to 4. This is the first point that we will get. Similarly, x plus y is equal to 4. We will substitute the value of y as 0 now in this given equation and we have the value of x as 4. These are the two points which we have found out. Let's make a table. When we substituted the value of x as 0, we obtain the value of y as 4 and when we substituted the value of y as 0, we obtain the value of x as 4. Now we need to plot these points on the graph. Let's have a graph. This is a graph which we have having the y-axis and the x-axis. This is the first, second, third and fourth coordinate and these are the points which we have already marked for you. Now the points which we need to mark are for x0, y4, for y0, x4. Now these points, when x is 0, y is 4. So the point will be here and we will be naming this point as 0, 4. We always write the value of x in front and then the value of y. And then we have x as 4 and y as 0. So the point will be here. This is 4, 0. Now we need to draw a line to join these two points. Now this line is representing equation x plus y is equal to 4. This is all what you were supposed to do in this question. I hope you enjoyed the session. Take care of your calculations. Bye for now.
