Slope formula is m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 given any two points(x_1, y_1) and (x_2, y_2). Your given points are (x_1, y_1)=(k, 2k) and (x_2, y_2)=(2k, 6k).

(k,2k), (2k,6k)
Use the point-slope formula
slope = ( change in y ) / ( change in x )
+m+=+%28+6k+-+2k+%29+%2F+%28+2k+-+k+%29+
+m+=+4k+%2F+k+
+m+=+4+
The slope is 4
