Ответ:
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
