Question

1.What is solution. of given pair of equations?. How many solutions are possible.
2. What is the area of triangle formed by given lines & X axis?
3.Write Coordinate of any two points which lie on graph 2x-y=2​
​

Answer 1

Answer:

1) x= 2 and y= 2 (by elimination method) , you can also do it by substitution method.

you can see 2/1 not equal to -1/1

as a1/a2 not equal to b1/b2

so a unique solution is there (condition for intersecting lines)

2) area of triangle= 1/2*b*h=1/2*3*2

= 3 units (as 1/2 and 2 get cut)

3) (3, 4) and (2, 2)
