Make an equation:
J = 1/2F - 10
Where 'J' represents Justin's age and 'F' represents his Father's age.
Plug in 12 for J:
12 = 1/2F - 10
Add 10 to both sides:
22 = 1/2F
Divide 1/2 to both sides or multiply by its reciprocal, 2:
F = 44

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.
