Question

Write an equation in point slope form? I think it’s b

Answer 1

The point-slope form:

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

9.

We have:

$(8,\ 3)\to x_1=8,\ y_1=3\\m=5$

Substitute:

$\boxed{y-3=5(x-8)}$

10.

We have:

$(-3,\ -5)\to x_1=-3,\ y_1=-5\\m=-\dfrac{2}{5}$

Substitute:

$y-(-5)=-\dfrac{2}{5}(x-(-3))\\\\\boxed{y+5=-\dfrac{2}{5}(x+3)}$
