Hlo pls make us clear 6,8 and 14

For 6, Option (d) is correct as a and b cannot be zero .So not all real numbers

for 8, Draw the line on cartesian plane, this will be right angle triangle with perpendicular as y axis and base as x axis and hypotenuse as line x+y=7 with height and base as 7. So area is 24.5

For 14. This can be solved by substituting the values of x and y from graph into equation x -y+1=0, Green line will satisfy it
