If possible please help!! Evens ONLY!!

Answer 1

10.) x-6

12.) -2x-5

14.) 1/4x-1

16.) 2/5x+1

18.) -1/4x+1/4

Explanation:

I used y2-y1/x2-x1 and was able to find all of the answers. Also checked them with a graphing calculator :)

Hope this helps!

Answer 2

You would use y2 - y1 / x2 - x1

Since you are trying to find the slope of the line...
