1. The problem statement, all variables and given/known data First off, this is a homework question, but an example so answer is given. need help understanding it. -Show that ht elines given by the equations below are coincident: L: 2x - y = 5 M: -4x + 2y = -10 Solution: Write each equation in slope-intercept form: L: 2x - y = 5 -y = -2x + 5 y = 2x - 5 M: -4x + 2y = -10 2y = 4x - 10 y = 2x - 5 Answer: The lines L and M have a slope of 2, and the same y intercept (0,5) so they are coincident. I dont understand how they got that answer of slope of 2 and y intercept of (0,5) ? 2. Relevant equations 3. The attempt at a solution Thanks everyone!
