there are a total of 45 slope questions for homework, 15 of each of the follwoing kind. School was dismissed early due to weather, and the Math teacher was unable to get to how we do this...but she still expects us to get it done. We have learned the slope formula, but i am not sure how to put in each numbers in the correct position:
question #1-
Find the value of K so that the line joining the points (-2, 7) and (3, K) is horizontal
Graphically, i found K=7, but we have to show it in algebraic form.
question #16-
Find the value of K so that the line joining points (1, -3) and (k, 5) is vertical.
Same situation as above, i found K=1 but have no clue how to do it algebraically.
question #31-
If the line joining points P(3,5) and Q(1,2) is paralell to line joining
R(7,K) and S(5,6), What is the value of K?
This one, i have no idea how to do at all!
any help greatly appreciated!!!
