 Question 292400: How do I find 3 ordered pairs and the x and y intercepts of 3x + y = 6? Teacher's directions: Provide an x/y chart and show your work in finding 3 ordered pairs. •Find the x and y intercepts of the equation. This is what I've got done so far. 3x + y = 6 lets say x=0 3 * 0 = 0 y = 6 (intercept at 0,6) 3x + y = 6 lets say y=0 y*0= 0 3*2 = 6 x=2 (intercept at 2,0) Now, I do not know how to find the third ordered pair.

 Question 291998: You have been hired by a group of anthropologists to sort out the data that they collected from a trip to Ja-Ji, a remote island in the south Pacific. The people of Ja-Ji do not permit outsiders to count them directly; so, the anthropologists had to collect all sort of other data to get to the population. They fear that they may have missed something and your job is to make that assessment, or better yet, use what they have to get the population of Ja-Ji. This is what their notes say: People in Ja-Ji are either single or in monogamous unions. 10% of the adult population of Ja-Ji is homosexual and they are all in long term relationships. These homosexual unions constitute one fifth of the unions in Ja-Ji. There are 1,000 children, which constitute half of the single population of Ja-Ji. Click here to see answer by marcia09(1)
