A triangle has vertices A(1, 1), B(2, 4), and C(4, 2). Line p is parallel to side AB and contains point C. Write an equation for line p by following the steps below. Part I: Find the slope of AB. Show your work. Part II: Use the slope from Part I and point C (4,2) to write an equation for line p in slope-intercept form. Show your work. Part III: Graph Triangle ABC and line p on the grid to show AB and line p are parallel. (You may use graph paper instead if you prefer).
