Answer 1

To find the coordinates of the intersection point, we can solve the system of equations:

2x + y = 15
y = -x + 5

We can solve this system by substituting the second equation into the first equation:

2x + (-x + 5) = 15
2x - x + 5 = 15
x + 5 = 15
x = 10

Now we can substitute this value of x back into either of the equations to solve for y. Let's use the second equation:

y = -x + 5
y = -10 + 5
y = -5

Therefore, the intersection point is (10, -5).
