Analyze the following graph and select the best match for the slope of the graph. 1/3 3 -1/3 -3 https://static.k12.com/eli/bb/1211/4_68960/2_33573_3_68963/bca78d55b205e10e6421f29b50ced960efb88a1b/media/d7d262058af97602d9effa86fbae1a6e32f4b842/mediaasset_1025083_1.gif

Nnesha (nnesha):

line is increasing or decreasing ?

Nnesha (nnesha):

|dw:1440945121141:dw| if line start from 3rd quadrant to 1st quadrant then line would be increasing

OpenStudy (surryyy):

oh ok

Nnesha (nnesha):

|dw:1440945214788:dw| if line start from 2nd quadrant to 4th quadrant then decreasing

Nnesha (nnesha):

so now look at the graph tell is it increasing or decreasing ?

OpenStudy (surryyy):

decreasing

Nnesha (nnesha):

yes right if line is decreasing then slope would be negative if line is increasing then slope would be positive

Nnesha (nnesha):

slope = rise /run |dw:1440945466511:dw| or you can pick two points to find slope

Nnesha (nnesha):

pick two points !

Nnesha (nnesha):

two points means (x,y)(x,y) two order pair

Nnesha (nnesha):

or you can use the formula `slope=rise/run` to find slope how many units it's going down from the y-intercept and then left ? |dw:1440945748106:dw|
