When looking for the point precisely in between two different points, the average of both coordinate points are taken. Since you are given 2 pairs of x and y coordinates, you just have to look for the average of the x-coordinates, and the average of the y-coordinates. To illustrate:

Midpoint = ( (a + c)/2 , (b + d)/2 )

Layla and Sam are both dog sitters. Layla charges $2 per day plus a sign-up fee of $3. Sam charges a flat rate of $3 per day. Th

Answer:

Layla charges $2 per day, plus a sign-up fee of $3. Notice the sign-up fee represents a fixed value, that's gonna be the constant form of the function. And $2 is the ratio of change of the function, because it a cost per day.
Sam charges $3 per day, without extra fee. So, the ratio of change of this function is $3, and it doesn't have a constant term.

According to the given information, the linear function for Layla is:

$f(x)=2x+3$

Notice that the constant ratio of change is coefficient of the independent variable, that is, because that variable represents days, and each charges $2.

On the other hand, the linear function for Sam is:

$g(x)=3x$
