While creating a map Louis used a grid system. Louis determined that his location was at the coordinates (250, 129). A pond, exactly halfway between Louis and the mountain, was at the coordinates (375, 694). What coordinates should Louis use to represent the mountain's location?
To calculate the coordinates of a midpoints, we use: (x , y) = ((x₂ + x₁)/2 , (y₂ + y₁)/2) Using this on the x-value fist: 375 = (250 + x) / 2 x = 500 On the y-value: 694 = (129 + y)/2 y = 1,259 The coordinates of the mountain are (500 , 1259)
