Write the slope-intercept equation for the line with slope -2/5 and y-intercept (0, -3)
y=-2/5x-3 :)
did you get this one bella?
actually i have 4 problems that i am stuck on no i haven't figured it out as yet
the formula is y=mx+b where m is the slope and b is the y intercept. since the slope is given and the y intercept is -3, then just plug in the values! :)
okY Phoebeco i get ya
just remember the formula y = mx + b m= slope ,,,,b= x intercept plug in the point(0,-3) y = (-2/5)x - 3 answer
wow this is not the answer i got lol
sure thing, bellarue! :)
good luck bella...lol
hey can you help me with one more prob
k what is it
one moment
Find the slope and y-intercept of the line in the given equation. y=3/4x - 2
Mark o you still there
im here
y=mx +b y=3/4x - 2 m=3/4 xint= -2
just use the same formula, y=mx+b, where m is the slope and b is the y intercept, then you'll see that the slope is 3/4 and the y intercept is -2 :)
always use the formula there..
you will always use that formula...lol
so the formula never changes right
yes it never change ..lol
i have no idea why i think it has to change
no it never change...lol
ok gimmie a sec
k
do you know of a program that will allow me to do graphs on my Laptop
http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html try this, it is an online application, though.
there are software here http://www.wolframalpha.com/input/?i=compute+1+-+3x+%3E%3Dto+10+and+7x-5+%3E+30
use that theres example there already
okay thanks a lot you guys are awesome
yw bella,,,,,,,good luck now
last question i promise the rest i can finish tomorrow or in a few hours since its almost 430 am here
bookmark those graphing softwares so that you wont loose them....lol
okY hold on let me do that now
oky done
click on that bella, that one is one of your prob
okay
question on graphing equation
go ahead.....
the problem is asking me to Write the slope-intercept form of the equation of the line shown in the graph
the graph shows these points
ok yes they are exactly that points..the slope intercept form is always y=mx +b
-7, 5 and -7,7 my equation would be -7x + 5y=7y+7x
wait is that points? like this?(-7, 5) and (-7,7 )
yes atleast thats what am reading on the graph
which graph? the one im showing you?
no dear a test sample from my book
ah..if you see like these (-7, 5) and (-7,7) these are only points in the graph
ok so i don't have to write and equation
yes,,..if they required you to write an equation from thay two points,,
okay
see this?(-7, 5) and (-7,7) , in my scratch paper they are vertical line if you join those two points.. and on vertical or horizontal line there is NO SLOPE OF THE LINE
okay am following
ok veryyyy goood......anything more? any question?
no tks your awesome and i am off to bed i have to be up in 3hrs
ok..thennn what states are you in?
ok good nityy now good luck.bella.....
thks coz am gonna need it
