9. A square with a perimeter of 20 units is graphed on a coordinate grid. The square is dilated by a scale factor of 0.7 with the origin as the center of dilation
if (x, y) represents the location of any point on the original square, which ordered pair represents the
coordinates of the corresponding point on the resulting square? ..
A. (20x, 20y)
B. (x + 20,y+20)
C. (0.7x,0.7y)
D. (x + 0.7, y + 0.7)

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
