In the xy-plane, the midpoint M of segment AB has coordinates (-1, 3). And point A has coordinates (-3,0). What is the x-coordinate of point B?

O -1
O 1
O 2
O 3

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
