On the coordinate plane, the vertical axis (up and down) is the y-axis and the horizontal axis (side to side) is the x-axis. However, when there is a horizontal line on the graph, it represents a value of y that is true for any value of 'x'. In the same respect, a vertical line is a value of x that is true for any value of 'y'. In the case of the point (5, -6), a horizontal line would have to be y = -6 in order to pass through the point and cross the coordinate plane from left to right.
Linear scale factor =1/2 volume scale factor=(1/2)³=1/8 the volume of the larger figure will be: volume=length*width*height volume=16×15×6 volume=1440 cubic inches thus volume of the small sink will be: 1/8×1440 =180 cubic inches
