For the second question choose two points and subtract your y values and x values within your ordered pair

  1. (10,50)(25,20)
        slope = (20 - 50) / (25 - 10) = - 30 / 15 = -2

    3. y = mx + b
       slope(m) = -2
       (25,20)...x = 25 and y = 20
       now we sub and find b, the y int
       20 = -2(25) + b
       20 = -50 + b
       20 + 50 = b
       70 = b
       ur equation is : y = -2x + 70

    4. it would be a negative association because there is a negative slope. A negative association is when one variable increases, the other one decreases.

    5. ?? there both negative
