What is the slope of a line parallel to the line whose equation is x+y=-7x+y=−7. Fully simplify your answer.

Question

I need help on a equation

Answer 1

x+y = -7

y =-x -7 has slope = -1

the slope of a line is the coefficient of the x term when the linear equation is solved for y

-x has an implicit coefficient of -1

any parallel line has the same slope = -1
