OpenStudy (misty1212):

lets go slow because this is not that hard, okay?

OpenStudy (misty1212):

first of all, do you think the slope will be a positive number or a negative number?

OpenStudy (misty1212):

if you don't know that is okay, say so and i will tell you which it is,then we can find it

OpenStudy (anonymous):

a negative

OpenStudy (anonymous):

@mathmath333

OpenStudy (mathmath333):

\[slope(m)=\frac{ y_1-y_2 }{ x_1-x_2 }\\(x_1,y_1)=(5,5)\\(x_2,y_2)=(10,1)\\\]

OpenStudy (anonymous):

in english please

OpenStudy (mathmath333):

its english

OpenStudy (anonymous):

idk how to do that

OpenStudy (mathmath333):

if u see ???? reload the page

OpenStudy (mathmath333):

can u tell what is \(y_1\)

OpenStudy (anonymous):

i can see it it just dont make sence to me

OpenStudy (mathmath333):

can u see the value of \(y_1\)

OpenStudy (anonymous):

5?

OpenStudy (mathmath333):

yes similarly \(y_2=1\) so what is \(y_1-y_2\)

OpenStudy (anonymous):

(5,1)

OpenStudy (mathmath333):

\(5-1=?\)

OpenStudy (anonymous):

4

OpenStudy (mathmath333):

good so similarly what is \(x_1-x_2\)

OpenStudy (anonymous):

10-1 = 9

OpenStudy (misty1212):

|dw:1419432701857:dw|

OpenStudy (anonymous):

????????????/

OpenStudy (misty1212):

a picture to help you visualize what you are computing

OpenStudy (mathmath333):

no thats \(x_2-y_2\), retry can u see \(x_1\) and \(x_2\)

OpenStudy (anonymous):

that confused me this is soooooo confusing and frustrating 5-10=5

OpenStudy (mathmath333):

\(5-10=-5\) so \(m=\dfrac{y_1-y_2}{x_1-x_2}\\ =\dfrac{5-1}{5-10}\\ =\dfrac{4}{-5}\\ \) u have to convert it into decimal

OpenStudy (mathmath333):

\[\frac{ -4 \times 2}{ 5\times 2 }=\frac{ -8 }{ 10 }\]

OpenStudy (mathmath333):

can u convert it into decimal

OpenStudy (misty1212):

right \[\color{red}{five}\] units down \[\color{blue}{four}\] units slope is \[-\frac{\color{blue}4}{\color{red}5}\]

OpenStudy (misty1212):

@katieekazoo do you see the "right 5, down 4" in the picture?

OpenStudy (anonymous):

-.8
