HELP ASAP PLEASE EXPLAIN PLEASE

Answer: (-2, -2)
Step-by-step explanation:
1) Line Q has slope 1 and crosses origin (0)
So, y-intercept is 0 and has slope 1
So, y = x + 0
2) Find slope of line P
-6-0/0-(-3) = -6/3 = -2
Line P crosses y-intercept (0, -6)
So, y = -2x - 6
Graph them, and they intersect at point (-2,-2)
