CAN SOMEONE PLEASE GRAPH THIS FOR ME & THANK YOU LIKE VERY BERRY MUCH! <3

OpenStudy (anonymous):

y=x/14 where x is the amount of time(in seconds) and y is the amount of new babies

OpenStudy (unklerhaukus):

a straight line y=mx+b where the slope is m, and the y-intercept is b

OpenStudy (unklerhaukus):

can you tell me the slope and y-intercept of y=x/14 ?

OpenStudy (anonymous):

let me tag you on my last question okay? :)

OpenStudy (unklerhaukus):

okay,

OpenStudy (unklerhaukus):

the slope m is sometimes written as rise/run if we set the run (change in x co-ordinate) to be one, then the rise will equal m We can use this to plot a point on the line

OpenStudy (unklerhaukus):

another point that can be found easily is the point where the y-intercept occurs, ie at the point (0,b)

Okay so far im with you! :) i get that rise over run thing!

OpenStudy (unklerhaukus):

a straight line can be draw including these two points, this is the equation of the line .

OpenStudy (anonymous):

so i can draw it on microsoft & put 2 points to be shown as the grapgh ttight & wait whats the eqaution of the line y=mx+b i know its in this form & it increases going up

OpenStudy (unklerhaukus):

actually i should have said "if we set the run (change in x co-ordinate) to be one, then the rise will equal m+b"

OpenStudy (anonymous):

so the euation is m+b=y? sorry im kinda confused now :(

OpenStudy (unklerhaukus):

for example y=3x+1 has slope 3 and y intercept 1 so we have the points (1,3+1)=(1,4) and (0,1)
