Answer: 918 is the constant of variation.
Step-by-step explanation:
Since, In see saw the weight (w) of an object is inversely proportional to the distance (d) from the seesaw support.
That is w ∝ 1/d
or w = k/d
where k is the constant of variation.
Here, The weight of Levon, w = 153 lb
And, his distance from the see saw support, d = 6 ft
Therefore. 153 = k/6
⇒k= 153 × 6 = 918
X=8
To find the X-intercept/zero, substitute Y=0
0= -3/2+12
Then Just solve for X
Graphing
rise/run
Well for a linear function you would use the formula y=mx+b
^ means to the power of with nothing after it, it's miss-used. Solving without the ^ symbol it is -2xy with the ^ symbol it's irrational and cannot be solved.
