Could someone explain why did the answer adds 22 in the formula? and why 6.4?

 

Question missing answer for: find a linear function that models the relationship between the two variables and describe the slope and intercept (For example, if  gives weekly pay P, as a function of number of units sold s, then the slope of 7.5 is the pay per unit sold and the intercept of 80 is the amount of the employees base pay each week.)

Find a formula that relates student’s height and his/her hand length, then use it to determine the height of someone with 7.75 inch hands. (plot on a graph, pick two points that would best represents the line of best fit).

Solution
Foom the given toble of hand length and hight
linear function that satiafies the given
we have a
þoint of hand length and hight ,
fln) = 6.4n+22

hang length (inches)
Now when hand length 775 inches
then hight = f(7:75) = 6.4× (F75) +2 2
12345678
= 71.6 inches
