Answer: 
Step-by-step explanation:
1. Substitute 
into first equation and solve for "x" in order to find the x-intercept of the first line:
2. Substitute 
into the first equation and solve for "y" in order to find the y-intercept of the first line:
Knowing that first line passes through the points 
and 
, you can graph it.
3. Substitute into second equation and solve for "x" in order to find the x-intercept:
4. Substitute into the second equation and solve for "y" in order to find the y-intercept of the second line:
Knowing that second line passes through the points 
and 
, you can graph it.
The solution of the system of equations is the point of intersection between the lines. Therefore, the solution of this system is:
Answer:
4
Step-by-step explanation:
AB = ![\sqrt{[(4-(-4)]^{2} - [1-(-3)]^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5B%284-%28-4%29%5D%5E%7B2%7D%20-%20%5B1-%28-3%29%5D%5E%7B2%7D%20%7D)
= 4
