Question

draw a graphs of the equations x-y+1=0 and 3x+2y-12=0. determine coordinate of the vertices of the triangle formed by these lines and the x-axis, and shade the triangular region

Answer 1

draw the graph taking the values above

Answer 2

x-y+1=0 (1)

3x+2y-12=0 (2)

From (1) x 1 2 3

y 2 3 4

x-y+1 =0

-y = -x -1

y = x + 1

Put x = 1

y = x + 1

y = 1 + 1

y = 2

Do as the same way ...

I hope u do it .....
