17.

The point-slope form:

y-y_1=m(x-x_1)

We have slope=m=8, and the point (-5, -3). Substitute:

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

18.

The formula of a slope:

m=(y_2-y_1)/(x_2-x_1)

We have the points (3, 4) and (15, 10). Substitute:

m=(10-4)/(15-3)=(6)/(12)=(1)/(2)

The point-slope form:

$\boxed{y-4=(1)/(2)(x-3)}$

or

$\boxed{y-10=(1)/(2)(x-15)}$
