Question

Graph y=10-2x under the domain 1,2,3,4,5

Answer 1

To graph y = -2x + 10 (this is y = 10 - 2x written in proper format) using the domain values 1, 2, 3, 4, 5, we must first create a table. Here is a suggested one:
x    y
1    8
2   6
3   4
4   2
5   0
Now that we have created a table, we can simply plot the coordinate points on a graph. Here is the completed graph:
