4. Draw L 1 through (-2, 1) with slope 3 2 , and draw L 2 through (-2, 1) with slope 2 3 - . 5. Write an equation in slope-intercept form for the line. ANSWER: x1, y1 = 0,3 x2, y2 = 2, -1 m= -1 – 3 = -4 = -2 y = -2x + 3 2 – 0 2 1 6. Write the equation in standard form using only integers. -2/3x + 4 x 3 2 y - = -2/3x -2/3x + y = -4 -3 (-2/3x + y) = -4 (-3) 2x – 3y = 12
