-5/8+(-8/5)= i do not understand how to solve this

first find a LCM or least common multiple

-25/40+(-64/40)=

add the numerators or top number

-88/40

then you simplify it

-2 8/40

-2 1/5

I hope this is good enough:

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)
