Answer:
Slope
Step-by-step explanation:
In the regression equation y=a+bx, y is dependent variable and x is independent variable. It means that due to change in x the y changes respectively. The "a" is intercept of the model and it shows the value of y when x is zero. The "b" is the slope of the model and it depicts the change in y due to unit change in x. The positive value of b means that as the x increases y also increases and as the x decreases y also decreases. The negative value of b means that as the x decreases y increases and as the x increases the y decreases.The sign of b shows the type of relationship between independent and dependent variable.

Answer:
6.7 seconds
Step-by-step explanation:
Juan= Paul-0.4
Paul=Terry+1.3
We can substitute Terry+1.3 for Paul since they are equal
juan=(Terry-0.4)+1.3
terry=5.8
juan=(5.8-0.4)+1.3
juan=6.7
