MEDAL + FAN AWAITINGGGGG



What is the slope of a line that passes through the coordinates two comma twelve and the coordinates negative one comma three?

Hint: Think rise over run.

-3
- 1/3
1/3
3

Answer 1

m(slope)=y2-y1/x2-x1=
plug in your givens and your done.

Answer 2

use the slope formula\[\huge{m=\frac{ y_2-y_1 }{ x_2-x_1 }}\]\[\huge{Let~say(2,12)=(x_1,y_2)}\]\[\huge{Let~say(-1,3)=(x_2,y_2)}\]Then,plug in the value into the slope formula\[\huge{m=\frac{ y_2-y_1 }{ x_2-x_1 }}\]\[\huge{m=\frac{ 3-12 }{ -1-2 }}\]\[\huge{m=\frac{ -9 }{ -3 }}\]Then,try to reduce the result.
We notice that -9 and-3 can be divide by -3.\[\huge{m=\frac{ 3\times-3 }{ 1\times-3 }}\]\[\huge{m=\frac{ 3\times\cancel{-3} }{ 1\times\cancel{-3} }}\]\[\huge{m=?}\]solve it @swaugh

Answer 3

is it 3
