Answer:
y = -x - 2
Explanation:
If line r is parallel to line q, they will have the same slope.
Rearrange line q to isolate “y”, which will give you line r in slope-intercept form: y = mx + b, where m is the slope.
5x + 5y = -9
5y = -5x - 9
m = -1
Use point-slope form:
Substitute the slope m = 1 and the point on line q, (-1, -1).
y - (-1) = -1(x - (-1))
y + 1 = -(x + 1)
y + 1 = -x - 1
y = -x -2
Therefore, the equation of line r is y = -x - 2.

Answer:
(-7,-15)
Step-by-step explanation:
We can substitute first y in the second y. Both equations are also functions. We can merge the equations.
Substitute x = -7 in any given equations. I will choose the second equation to substitute in.
<u>Answer</u><u> </u><u>Check</u>
Substitute both x and y in both equations.
The equation is true for (-7,-15).
The second equation is true for (-7,-15).
Therefore our answer is (-7,-15)
