NEED THE EQUATION Elizabeth wants to ride her bicycle 28.6 miles this week. She has already ridden 19
miles. If she rides for 3 more days, write and solve an equation which can be used to
determine m, the average number of miles she would have to ride each day to meet
her goal.

Step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

the answer is here: : )
