find the slope of a line if x=3 and y= x (in terms of rise and run)

OpenStudy (anonymous):

1

OpenStudy (anonymous):

so the slope of the line is 1

OpenStudy (anonymous):

ya

OpenStudy (anonymous):

@mathquest do u have options

OpenStudy (anonymous):

typing error. I meant X=3 and Y=8

OpenStudy (anonymous):

8/3

OpenStudy (anonymous):

No options

OpenStudy (anonymous):

Does it pass through origin

OpenStudy (anonymous):

I mean the line

OpenStudy (anonymous):

no

OpenStudy (anonymous):

then the slope is not 8/3

OpenStudy (anonymous):

how do I solve it..not sure

OpenStudy (anonymous):

slope= (8-constant)/3

OpenStudy (anonymous):

I think, slope = (8-y)/(3-x)

OpenStudy (anonymous):

post your complete question

OpenStudy (anonymous):

AT first, do u know that slope =rise/run

OpenStudy (anonymous):

so the 8 is how far it rises on the y axis and the run is how far it goes on the x axis is this right?

OpenStudy (anonymous):

very right

OpenStudy (anonymous):

so would I be right to say that the graph rises? for every 3 units of run

OpenStudy (anonymous):

Rises 8

OpenStudy (anonymous):

nope....... it depends

OpenStudy (anonymous):

whether is passes through origin or not

OpenStudy (anonymous):

it crosses the y axis at 8

OpenStudy (anonymous):

therefore i think that it decreases right?

OpenStudy (anonymous):

And does it cross x-axis at 3

OpenStudy (anonymous):

yup
