Draw the goraph of linear equation x +2y=8 from
the graph drawn, check whether (-1,-2) is a solution
of this equation.
Answers
Answer:
The given equation is:
x+2y=8………..(1)
or, x/8 + y/4 =1…..(2) [dividing both sides of equation (1) by its R.H.S, i.e, by 8]
From eqn. (2), we can say that it is the equation of a straight line passing through the points (8,0) and (0,4).Therefore, to draw this straight line, just draw a line through these two points and extend it on both sides of those two points.
Now, if you plot this straight line in a graph paper, you will find that the straight line drawn doesn't pass through the point (-1,-2). It means that (-1,-2) is not a solution to equation (1). You can also verify this statement by putting x=-1 and y=-2 in eqn. (1). If we put x=-1 and y=-2 in eqn. (1), we get, -5=8 which is impossible. So, (-1,-2) is obviously not a solution to eqn. (1).
