In Exercises 9 to 24, find an equation of the line described. Leave the solution in the form Ax+By = C .The line has intercepts a = 2 and b = - 2 .

To determine

Find the equation of the line which has intercepts a=2 and b=-2.

Explanation

If a and b are the X and Y intercepts of a line then the equation of the line can be written as,

xa+yb=1

Substitute a=2 and b=-2 in xa+yb=1

x2+y-2=1

Using -2 LCM on left hand side x2+y-2=1 can be modified as,

-x
