    Hi. Can you please grade 5. Thanks.

    1. Line passes through the point (5,1) and has a slope of 2 write an equation for this line

    Solution:
    y-1 = 2(x-5)
    y-1 = 2x - 10
    y = 2x -9

    2. Find the equation for the line 1,-5 and -4,3

    Solution:
    Find gradient: (3-(-5)) / (-4-1) = -8/5

    Equation: y -3 = -8/5 (x-(-4))
    y-3 = -8/5 (x+4)
    y-3 = (-8/5)x - (32/5)
    y = (-8/5)x - (17/5)

    3. Find the equation for the line -2,-1 and -3,4

    Solution:
    Find gradient: (4-(-1)) /(-3-(-2)) = -5

    y-4 = -5(x-(-3))
    y-4 = -5(x+3)
    y-4 = -5x - 15
    y=-5x - 11

    4. Write equations for the horizontal and vertical lines passing through point (-1,9)

    Solution:
    Equation of horizontal line: y= 9

    Equation of vertical line: x = -1

    5. Consider the line -8x-2y=-5 what is the slope of the line perpendicular and parallel line

    Solution:
    2y = -8x + 5
    y = -4x + (5/2)

    Slope of the parallel line is: -4
    Slope of the perpendicular line is: 1/4

    Note that: If you multiply the slope of the parallel line and the slope of the perpendicular line, you must get -1
