a=-2

Step-by-step explanation:

If a line segment has one endpoint on the line y=x, then its coordinates are (b,b). The first endpoint of the segment is at point (a,0). We can find the coordinates of the midpoint of this segment as the average value:

$x_{\text{midpoint}}=\dfrac{x_{\text{first endpoint}}+x_{\text{second endpoint}}}{2},\\ \\y_{\text{midpoint}}=\dfrac{y_{\text{first endpoint}}+y_{\text{second endpoint}}}{2}.$
