slope = - 1

y-intercept = 7

#### Explanation:

one form of the equation of a straight line is y = mx + c where m =slope and c is the y-intercept.

rearranging the equation x + y = 7 into this form gives :

y = - x + 7

comparing the 2 equations we see that m = - 1 and c = 7

here is the graph of y = - x +7
