Given the equation y = -¼x -5. Write an equation,in slope-intercept form, of a line that is perpendicular and goes through the point ( 4, 3). (Hint: use y = mx + b, substitute the given point then solve for b. Then don't forget to take the negative reciprocal to the line perpendicular to the given line.)
