It is not true because if you add in 0 the equation would be 8-4(0)=4(0)
4x0 = 0
so it would be 8-0=0 which doesn't add up.
The velocity when the object falls from 84 feet is 73.32 ft/sec
Step-by-step explanation:
The formula is derived from the conversion of energy principle. As the object falls the potential energy changes into kinetic energy. The right formula is:

here,
v represents the velocity
and
h represents the height in feet.
We can plug in the value of height in the formula to get the value of velocity
So, Putting h=84

Rounding off to nearest 100th
v=73.32 ft/sec
The velocity when the object falls from 84 feet is 73.32 ft/sec

We know that
the equation of the line in standard form is
Ax+By=C
the equation of the line <span> in the slope-intercept form is
</span><span>y +1 = 2/3 (x - 8)-----> y+1=(2/3)x-(16/3)----> y-(2/3)x=(-16/3)-1
</span>y-(2/3)x=(-19/3)----> multiply by 3-----> -2x+3y=-19
the answer is
-2x+3y=-19
<span>I verify that the points belong to the given line
for the point (8,-1)
-2*8+3*(-1)=-19--------> -16-3=-19-----> -19=-19------> is ok
for the point (2,-5)
-2*2+3*(-5)=-19------> -4-15=-19------> -19=-19-----> is ok</span>
