Explanation: First, we will need to get the coordinates of points M' and N': We are given that the dilation factor (k) is 0.8 Therefore: For point M': x coordinate of M' = k * x coordinate of M x coordinate of M' = 0.8 * 2 = 1.6 y coordinate of M' = k * y coordinate of M y coordinate of M' = 0.8 * 4 = 3.2 Therefore, coordinates of M' are (1.6 , 3.2)
For point N': x coordinate of N' = k * x coordinate of N x coordinate of N' = 0.8 * 3 = 2.4 y coordinate of N' = k * y coordinate of N y coordinate of N' = 0.8 * 5 = 4 Therefore, coordinates of M' are (2.4 , 4)
Then, we can get the slope of M'N': slope = (y2-y1) / (x2-x1) For M'N': slope = (3.2-4) / (1.6-2.4) slope = 1
