OpenStudy (bloomlocke367):

well, you first need to find the equation of the line for relationship a. do you know how to do that?

OpenStudy (anonymous):

no probably find the slope

OpenStudy (bloomlocke367):

yes.. you need to find the slope :) do you know how? \[slope=\frac{ rise }{ run }\]

OpenStudy (anonymous):

i dont know if i add or subtract

OpenStudy (bloomlocke367):

what do you mean? add or subtract what?

OpenStudy (anonymous):

ok how do i find the slope of the 4 numbers

OpenStudy (bloomlocke367):

oh. honestly, since you have the graph, you don't need to use the points to find slope.

OpenStudy (anonymous):

but its easier for me that way

OpenStudy (bloomlocke367):

BUT, since you asked slope (m)\[m=\frac{ y_2-y_1 }{ x_2-x_1 }\]

OpenStudy (anonymous):

thank u thats what i needed

OpenStudy (anonymous):

@BloomLocke367 i still dont understand

OpenStudy (bloomlocke367):

what don't you understand? tell me what you get for the slope.

OpenStudy (anonymous):

4,2

OpenStudy (bloomlocke367):

what?

OpenStudy (bloomlocke367):

you should plug these numbers in:\[m=\frac{ 4-2 }{ 8-4 }\]\[=\frac{ 2 }{ 4}\]\[=\frac{ 1 }{ 2 }\]

OpenStudy (bloomlocke367):

then you just have to pick the slope(s) that are steeper than that.

OpenStudy (anonymous):

oh ok

OpenStudy (bloomlocke367):

let me know what you get. :)
