slope = - 1 , y-intercept = 1

#### Explanation:

One form of the equation of a straight line is y = mx + c ,where m represents the gradient ( slope ) and c the y-intercept.

Rewriting the equation x + y = 1 in this form gives : y = - x + 1 .

By comparison of the 2 equations we obtain slope = - 1 and c = 1 .
