Find the equation of the line that contains the ordered pairs given on the table

x : 4,5,7
y: 3,3,3

Step-by-step explanation:

If you were to plot these coodinates on an x-y coordinate plane, you would see that it is a perfectly horizontal line through y = 3.  The x coordinates can range from negative infinity to positive infinity, but every x value has a y coordinate of 3. That, then, is the equation of the line.  y = 3
