Write the equation of the line where m=-1 and passes through the point (-2,4) (y=mx+b)

1. 4=-1*(-2)+b，4=2+b，b=2，y=-x+2， x+y-2=0

2.beacuse of m=-1

x+y=2,x+y-2=0

(See which one you think better understand)

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
