How do I convert standard form to point slope

Fittoniya [83]

The point-slope form:

$y-y_1=m(x-x_1)$

$(x_1,\ y_1)$ - given point

$m$ - given slope

The standard form:

$Ax+By=C$

$y-y_1=m(x-x_1)$ <em>use distributive property</em>

$y-y_1=mx-mx_1$ <em>add $y_1$ to both sides</em>

$y=mx-mx_1+y_1$ <em>subtract $mx$ from both sides</em>

$-mx+y=-mx_1+y_1$ <em>change the signs</em>

$mx-y=mx_1-y_1$
