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

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.

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.

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
