Math 9th grade slopes
posted by Chelsea on .
A line connecting (5, 6) to another point has an undefined slope. What is the closest point on this line with whole number coordinates below (5, 6)?
since the slope is undefined, the line must be vertical.
Clearly the point with integer coordinates just below (5,6) would be (5,5)
A line with a slope of -2 passes through the point (1, 7). What is the closest point on the line above (1, 7) which has whole number coordinates?
