## anonymous one year ago Which line has a slope of 1/3 ?

y=mx+b m is the slope so whichever line has something along this: y=1/3x + b has a slope of 1/3

3. AbdullahM

Do you know the slope formula?

yes

Line B by inspection.

7. anonymous

but it looks as if line B has that slope but not exactly i can't figure it out

A is -1/3

Slope formula= $$\sf\Large \frac{y_2-y_1}{x_2-x_1}$$ So, you can see which points are on the line and calculate the slope.

if you take points (-5,-4) and (6,0) you don't get a slope of 1/3 but by looking at the graph it looks like the slope would be 1/3......

This line has a slope of 1/3 |dw:1435337829795:dw|
