1. The problem statement, all variables and given/known data In a cartesian coordinate system, two lines r and s, with angular coefficients 2 and 1/2, respectively, intercept at the origin. If B [itex]\in[/itex] r and C [itex]\in[/itex] s are two points in the first quadrant such that the line segment BC is perpendicular to r and the area of the triangle OBC is 12x10-1, then what is the distance from point B to the y axis? 2. Relevant equations 3. The attempt at a solution Okay, first I found the relationship between OC and BC using the formula for the area of a triangle: [OBC] = 12x10-1 = 12/10 = 6/5 = (OB BC)/2 Now I am stuck. Whatever I do it seems like I am going around in circles..
