Take a point A on X -axis and B on Y - axis and find area of the triangle AOB . Discuss with your friends what did they do `(AS_(3))`

Does y = x + 7 represent a straight line ? Draw the line on the coordinate plane . At which point does this line intersect Y-axis ? How much angle does it make with X - axis ? Discuss with your friends . (AS_(3),AS_(5))

Give any five examples of points on Y-axis and X-axis.

Let A (x_(1),y_(1) ) , B(x_(2),y_(2)) , C (x_(3) , y_(3)) . Then find the area of the following triangles in a plane . And discuss with your friends in groups about the area of that triangle
