The graph shows a scatter plot and line of the best fit relating the ages of children and the total number of times they have visited the doctor. use the line of best fit to estimate the age of a child who has visited the doctor 40 times. a. 14 years old b. 11 years old c. 12 years old d. 13 years old

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

b.   e = 7.5h

hope this , lovely!

this cant be answered without the graph. you may need to add it.
