for any positive integer like 4, the value of 4! is 4 x 3 x 2 x 1. What is the greatest common factor of 6! and 5! ?

4. (10.03 mc) the equation of line cd is y = −2x − 2. write an equation of a line parallel to line cd in slope-intercept form that contains point (4, 5). (4 points) y = −2x + 13 y = negative 1 over 2 x + 7 y = negative 1 over 2 x + 3 − 2x − 3
