Solve the pair of equations $\displaystyle x=3$ and $\displaystyle \mathrm{y}=-4$ graphically.Using graphical method, find whether following system of linear equations is consistent or not : \[x=0 \text { and } \mathrm{y}=-7 \]
Solve the pair of equations $\displaystyle x=3$ and $\displaystyle \mathrm{y}=-4$ graphically.
Using graphical method, find whether following system of linear equations is consistent or not : \[x=0 \text { and } \mathrm{y}=-7 \]
Marking-scheme solution
Solution of equation is \(\displaystyle \mathrm{x}=3, \mathrm{y}=-4\)
As \(\displaystyle \mathrm{y}=-7\) is intersecting \(\displaystyle \mathrm{x}=0\) at ( \(\displaystyle 0,-7\) )
So, system of equations is consistent
