Which of the following of the line with a slope of 7 that passes through the point (1/2, 3/2) a. y= 7x - 11
b. y= 7x - 10
c. y= 7x - 5
d. y= 7x -2

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

leave feedback if u need : )

the correct answer is the last option

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.
