Straighten a line for me??

[LWoods]

I found an svg file that I wanted to use for my daughters bday invite, I have removed a section of the picture that I didn't want to use but I don't have enough skill to straighten the lines, can anyone do this for me??

Will this work?

That is exactly what I wanted! THANK YOU SO MUCH!!
