## anonymous one year ago Find the slope of the line below. If necessary, use a slash (/) to indicate a division bar. http://media.apexlearning.com/Images/200706/18/009fb4dc-a2d3-4ea3-8f39-62f73e08e8de.gif m=

The slope of any line is defined by the difference between the y-coordinates of the points divided the difference between the x-coordinates, so, the formula looks like this: $m _{ab}=\frac{ y_2-y_1 }{x_2-x_1 }$ So, applying it for the points: $m=\frac{ 4-(-4) }{ 3-(-1) }$ So, all you have to do is operate the fraction and see what you obtain as a result.

6.3 ?

4. Owlcoffee

Not really, first off you have to operate the multiplication of negatives on both the numerator and denominator: $m=\frac{ 4-(-4) }{ 3-(-1) }$ $m=\frac{ 4+4 }{ 3+1 }$

5. anonymous

so is that the answer ? ^

6. Owlcoffee

No, you have to sum 4+4 and divide it by 4.

2

8. Owlcoffee

that's correct.

9. anonymous

so m=2

10. anonymous

?

11. Owlcoffee

Yes.

12. anonymous

Thanks

@Owlcoffee _____ is the difference in x-coordinates ?

14. Owlcoffee

No, the difference between the x coordinates is "x2-x1" which is below the division line.
