what is the rate of change in dollars per hour if plumber charges 130.00 for 2 hrs work and 235.00 for 5 hrs work

18

Step-by-step explaition:

130 divided by 2 is 65 235 divided by 5 is 47 65 - 47 is 18

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)
