Triangle x y z is shown. angle z w x is a right angle. an altitude is drawn from point w to point y on side z x to form a right angle. the length of w y is 4, the length of y x is a, the length of z y is 3, the length of z w is c, and the length of w x is b. what is the value of a? 5 units 5 and one-third units 6 and two-thirds units 7 units

49/6 is going to equal 8 1/6

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
