How many equal sections divide a directed line segment if it is to be partitioned with a 7: 10 ratio?

c(0,-8) and d(-4,10) are the endpoints of a line segment. what is the midpoint m of that line segment?

find slope given the points (2, 5) and (4, -7)

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
