Put the amount you go up or down on the Y-axis over how much you go right or the x-axis
the Y-intercept is found simply by looking where the graph crosses the y, if the equation is written instead of graphed, graph it using a graphing calculator, then use the information I gave you previously : )
Coordinates of the midpoint of AC: M ( (-6-2) / 2) , ( 7-9 ) /2 ) = ( -4, -1 ) d ( BM ) = √ ( 4 + 4 )² + ( -1+ 1 )² d ( BM ) = √ 8 ² =√ 64 = 8 The length of the median from angle B is 8.
