Final answer:
The y-intercept of the line x+2y=-14 is the point (0, -7), which is where the line crosses the y-axis.
Step-by-step explanation:
To find the y-intercept of the line given by the equation x + 2y = -14, we can set the value of x to 0, because the y-intercept occurs where the line crosses the y-axis. Solving for y when x is 0 gives us:
0 + 2y = -14
2y = -14
y = -14 / 2
y = -7
Therefore, the y-intercept is the point (0, -7).
