The sum of two numbers is 25. What are the numbers?

a. Create an equation using two variables to represent this situation. Be sure to explain the meaning of each variable.

Let x and y be real numbers such that

x+y=25

b. List at least 3 solutions to the equation you created in part (a).

x=12, y=13

x=-2, y=27

you can do the last one yourself

c. Create a graph that represents the solution set to the equation.

You can graph the points on a number plane and see what shape you get.

Join them all up and you have your graph. :)

(a) x+y=25, both are addends that make up the sum.

(b) x=6, y=19

x=10, y=15

x=16, y=9

(c) Graph it on a data line.  May 22, 2018
