To find solutions to an equation, we can choose any values for x, and then use the equation to find the value of y to make an ordered pair in the form (x,y).
First, let's choose x = 1.
y = 3(1) + 4 = 7
The ordered pair is (1,7)
Let's choose x = 4.
y = 3(4) + 4 = 16
The ordered pair is (4,16)
Let's choose x = 11
y = 3(11) + 4 = 37
The ordered pair is (11,37)
The three solutions we found are:
(1,7)
(4,16)
(11,37)
Note that we could choose any values for x that we like. In this case we chose x = 1, x = 4, and x = 11, but any values of x will work fine.
