The sum of my numbers ($$) is 6.7, and their difference ($$) is 4.3. What are my two numbers?

this doesn't make sense lol

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.

step-by-step explanation:

it has the same slope and a different y-intercept

hope this : )
