Yes, it passes the vertical line test
Y = -7
x = -19
Steps:
Add the two equations together:
y - x + y + x = -14
2y = -14
y = -7
-7 + x = -26
x = -19

What lesson are you working on ? because there are different formulas to find the solutions for a triangle
Answer:

Step-by-step explanation:
The formula for point slope is: 
When:
m = slope
(x1,y1) = the point on the graph
-9 is the slope, so it replaces m. x1 is -1, and y1 is -3.
Plug in the values:
