find an equation of the line containing the given pair of points (-7 -7) and (5 5)

Thank you for the opportunity to help you with your question!

k=(y2-y1)/(x2-x1)=(5+7)/(5+7)=1

thus assume the equation y=x+b, plug in (5,5) we get:

5=5+b, b=0

thus the answer is y=x

Please let me know if you need any clarification. I'm always happy to answer your questions.
