The map of a walking trail is drawn on a coordinate grid with three points of interest. the trail starts at r(−2, 4) and goes to s(3, 4) and continues to t(3, −1). the total length of the walking trail is units. (input whole numbers only.) (15 points on the line)

10 units

Step-by-step explanation:

Using a corrdinate grid, you can plot the points to find the distance between each one to get your answer.  You can also look at the points given:

R(-2, 4) to S(3, 4) = moves in a straight line east (right) for a total of 5 units

S(3, 4) to T (3, -1) = moves in a straing line south (down) for a total of 5 units

5 units + 5 units = 10 total units of walking trail
