I believe the probability is 1/2
You can see that there is a proportional relationship between X and Y because every 6 of X decreases 3 in Y. In that way you can say is a linear relationship and you can construct a linear equation: Now, to calculate the equation you use: (Y - y1) = y2 - y1 (X - x1) x2 - x1 Let's peek two pairs (1,-4) and (7,-7) (Y - (-4)) = (-7 - (-4)) (X - 1) (7 - 1) <span>Y + 4 = -3 (X - 1)</span> 6 If you want to express the equation as aX + bY + C = 0 Y + 1/2 X + 7/2 = 0 If you want to express the equation as Y= ax + b <span>Y = -1/2X - 7/2</span>
