Answer:

y = -x - 9

Explanation:

The slope of the given line is -1

The coordinate given is ( -7 , -2 )

Since the line is parallel, we can plug in the slope into the equation:

y = -1x + b, simplified to y = -x + b

To calculate the y-intercept, you simply put the coordinates into the equation and solve for b:

-2 = - ( -7 ) + b

-2 = 7 + b

-2 - 7 = b

-9 = b

Now put the b value into the equation and you have the answer:

y = -x - 9
