What is the y-intercept for line A, considering these answers (0,1/2),(1/2,0), (0,-1) and (-1,0).
To find the y-intercept, we need to find the point on the line where x equals zero (x=0). In other words, we need to find the value of y when x is zero.
Let's go through each answer point and check if x is zero.
For the point (0, 1/2), x is zero, so this could be the y-intercept.
For the point (1/2, 0), x is not zero, so this point cannot be the y-intercept.
For the point (0, -1), x is zero, so this could be the y-intercept.
For the point (-1, 0), x is not zero, so this point cannot be the y-intercept.
Since the y-intercept is the point where x equals zero, we can conclude that the y-intercept is either (0, 1/2) or (0, -1).
The final answer is: The y-intercept for line A is either (0, 1/2) or (0, -1).
By checking if the x-coordinate is zero for each given point, we were able to identify the potential y-intercept points.
