yes I need help creating equation
OpenStudy (anonymous):
standard form = Ax + By = C
Nnesha (nnesha):
make two order pair (x,y)(x,y)
Nnesha (nnesha):
yes use that data to find slope
time represent x values y represent velocity
OpenStudy (anonymous):
(2, 54) and (4, 58)

Nnesha (nnesha):
yep :-)
OpenStudy (anonymous):
ok give me a sec to calculate slope
Nnesha (nnesha):
:-) okay
OpenStudy (anonymous):
slope is 2?
(58-54)/(4-2)
4/2
2
Nnesha (nnesha):
yep right so slope is 2
y = mx + b
where m is slope which is 2
y = 2x +b
use one of order pair and substitute x and y values into the equation then solve for b

54 = 2(2) + b
or
58 2(4) + b
OpenStudy (anonymous):
forgot the = sign on the second one
OpenStudy (anonymous):
I am choosing the first one so do I solve for B?
Nnesha (nnesha):
yep
OpenStudy (anonymous):
ok
52 = 2(2) + b
52 = 4 + b
52 + -4 = 4 + b + -4
48 = b

Nnesha (nnesha):
52 ? :O
OpenStudy (anonymous):
oh whoops
OpenStudy (anonymous):
54 haha let me redo that
Nnesha (nnesha):
okay :-)
OpenStudy (anonymous):
54 = 2(2) + b
54 = 4 + b
54 + -4 = 4 + b + -4
50 = b

Nnesha (nnesha):
yep right so equation in slope intercept form is y =2x + 50
now subtract 2x both side
OpenStudy (anonymous):
y = 2x + 50
y - 2x = 2x + 50 -2x
y - 2x = 50
Nnesha (nnesha):
yep -2x + y =50
x comes first
OpenStudy (anonymous):
yeah, so that is my equation for both or just one?
Nnesha (nnesha):
what do you mean both ?? or one ?

OpenStudy (anonymous):
haha nvm confused myself for a second
OpenStudy (anonymous):
so that's it for part 1 besides defining the variables
Nnesha (nnesha):
part ONE = DONE
OpenStudy (anonymous):
yay let me see if I can do part 2 tell me if it is good give me a sec
OpenStudy (anonymous):
To find this out, we first change our equation to slope-intercept form.
-2x + y = 50
-2x + y + 2x = 50 + 2x
y = 2x + 50
Now, since we got that done, we plot our y-intercept, 50. Now from this point, we go up 2 units then right 1 unit since our slope is 2. That is our next point and also the first our. We do this 6 more times and that's the first 6 hours.

OpenStudy (anonymous):
right?
OpenStudy (anonymous):
How can you graph the equation obtained in Part A for the first six hours?
OpenStudy (anonymous):
or do I need to plug in 6 in the equations somewhere?
Nnesha (nnesha):
like you have to keep doing this (up 2 right one ) until 6 h
OpenStudy (anonymous):
so my answer is right

for y -intercept just write (0 , 50) just to explain a little bit more that y-intercept on y-axis when x =0
OpenStudy (anonymous):
yeah understandable
Nnesha (nnesha):
y-intercept is always on y-axisss when x =0
OpenStudy (anonymous):
yup
Nnesha (nnesha):
yep _-_ :-)
