Find the greatest possible value of a if the distance between line l_1: 2x+3y-6=0 and line l_2: 4x+6y+a=0 is 5√(13)26. ( ) A. -17 B. -7 C. -20 D. 7 E. 17
Added by Joshua H.
Step 1
We know that the slope of l_1 is -2/3, so the slope of the perpendicular line is 3/2. Using the point-slope form, we get the equation y = (3/2)x. Show more…
