 Question 534859: Given the eqation y=4x-6 write the equation of a line that has been shifted down 3 units. Answer by fcabanski(889)   (Show Source): You can put this solution on YOUR website!Check my profile and contact me for one on one online tutoring. Look at what happens at the y-intercept (when x is 0): y = 4*0-6 = -6. How do we shift that point down 3 units? In other words, how do we make y = -9 when x=0? -9 = 4*0-6+c where c is a constant. ---> -3 = c ---> so we subtract 3 from the constant in this equation. y = 4x - 6 - 3 = 4x -9 The equation of the line shifted down 3 units is y=4x -9.
