what do we already know from the graph:
we know the slope is negative since the line is sloping down and that the y intercept is (0,6)
that leaves only two answer choices
do you know how to find slope?
OpenStudy (sparklestaraa):
y=mx+b
(0,6)=
OpenStudy (acxbox22):
(0,6)= y-intercept
the slope from the graph we can find by using rise/run
we can see it goes down 2 and right 3
so that is -2/3 <<<< this is the slope
what is the answer now?
OpenStudy (sparklestaraa):
oh isn't it like (0.-6)=-2/3x+b?
OpenStudy (acxbox22):
no in the equation y=mx+b
b is the y value of the y intercept

how can you find the y value of a y intercept?
OpenStudy (acxbox22):
we already know the y intercept is (0,6) 6 is the y vale of the y intercept so b=6
OpenStudy (sparklestaraa):
ohh so (0,6)=-2/3x+6 ?
OpenStudy (acxbox22):
no the equation is simply y=-2/3x+6
remember (0,6) does not equal y so you dont put it there
you just leave the y there to get your equation
OpenStudy (sparklestaraa):
ohhh thanks :D i understand that now :D
