Answer:

(1) 2, (2) -5/4, (3) 7/5, (4) -7/4, (5) 3/5, (6) -1/4, (7) 3, (8) -1/2, (9) 1/6

Step-by-step explanation:

each line had points on it. what you want to do is go to the bottom point. then go up until you hit the line where the other point is. then go to the side to where the other line is. make sure you're counting the whole time. if it can be simplified (ex: 2/4), simplify it. if the line is pointing to the left, it is negative. remember, rise over run, if pointing left it's negative, and draw a triangle from the points (which i didnt say but it works).

If y varies directly as x and y=14 when x= 3.5 what is the constant of variation
gulaghasi [49]

Hey there! Direct variation, a concept commonly applied to linear equations.

The constant of variation is a concept which simply refers to the change in y, based on the change in x. If this change is constant, then it is a constant of variation.


You can find the constant of variation (usually referred to as 'k') by dividing any point's y-value by its x-value.


In this instance, we have the point (3.5, 14)

14 / 3.5 = 4


The constant of variation for this equation would be 4.
