To find the intersection point, we need to solve the system of equations:
1) 2x + y = 15
2) y = -x + 5
Substitute equation 2 into equation 1:
2x + (-x + 5) = 15
2x - x + 5 = 15
x + 5 = 15
x = 10
Now, substitute x = 10 into equation 2 to find y:
y = -10 + 5
y = -5
Therefore, the intersection point is (10, -5).
1) 2x + y = 15
2) y = -x + 5
Substitute equation 2 into equation 1:
2x + (-x + 5) = 15
2x - x + 5 = 15
x + 5 = 15
x = 10
Now, substitute x = 10 into equation 2 to find y:
y = -10 + 5
y = -5
Therefore, the intersection point is (10, -5).
