What is the scale factor from figure A to figure B

Polygon mnopq is dilated by a scale factor of 0.8 with the origin as the center of dilation, resulting in the image m′n′o′p′q′. the coordinates of point m are (2, 4), and the coordinates of point n are (3, 5). the slope of is .

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
