$\large\color{slate}{ \displaystyle y-y_{_{^1}}= m\left( x-x_{_{^1}} \right)                   }$

solomonzelman · Answer

Where, $\large\color{blue}{ \displaystyle \left(x_{_{^1}},y_{_{^1}} \right)    }$ is the point and $\large\color{blue}{ \displaystyle m   }$ is the slope.

anonymous · Answer

so m=-4

solomonzelman · Answer

yes.

solomonzelman · Answer

can you fill in the    $\large\color{slate}{ \displaystyle y-y_{_{^1}}= m\left( x-x_{_{^1}} \right)                   }$  ?

anonymous · Answer

is it y=-1x+5

@satellite73 may you help me please

solomonzelman · Answer

$\large\color{slate}{ \displaystyle y-y_{_{^1}}= m\left( x-x_{_{^1}} \right)                   }$


$\large\color{slate}{ \displaystyle y-(5)= -4\left( x-(-1)\right)                   }$

solomonzelman · Answer

you need to convert to:
$\large\color{slate}{  y=mx+b    }$

that is all.
