Question 468479
y = x - 2; (3,1)
1 = 3 - 2 {substituted 3 in for x and 1 in for y}
1 = 1 {this is a true statement, therefore it is a solution}


y = x - 2; (-2,-4)
-4 = -2 - 2 {substituted -2 in for x and -4 in for y}
-4 = -4 {this is a true statement, therefore it is a solution}


Graphing:
- there are several ways to do this, so it is up to you
- an easy way to get another point without graphing is to 
substitute any number in for x, other than 3 and -2 (those were used above)
