1. Write an equation in slope-intercept form for the line that passes through (3,5) and (-2,1).

2. Describe the system 6x-2y=10 and 9x-3y=8 as consistent and independent, consistent and dependent, or inconsistent. Explain

    1. The slope-intercept form is
    y = mx + b
    Write these two equations that must be satisfied for the two points:
    5 = 3m + b
    1 = -2m + b
    Subtract the second from the first:
    4 = 5m m = 4/5
    5 = 12/5 + b
    b = 13/5 etc.

    2. Multiply the first equation by 1.5 and get
    9x - 3y = 15
    This is inconsistent wth the second equation. They repreesnt two parallel lines. They cannot both be satisfied at any point in (x,y) space.
