How many ways can you order the digits 2,3,4 and 5. you can only use each number once?

These Lines will be parallel.

Step-by-step explanation:

You have to find the slope of each line. For (1,1) and (3,3) the slope is 1 and for Line 2 the slope is also 1. (let me know if you want me to show the work for slope). To have parallel lines the slopes have to be the same and y-ints have to be different. Here the slopes are the same and in Line 1 the yint is (0,0) which is different than Line 2. Therefor the Lines are parallel.  

Sorry if im wrong!. Hope this helps
