Question

Select the equation of the line that passes through the point (–2, 1) and has slope 3 in point-slope form.

Answer 1

y-y1 = m(x-x1)
y-1 = 3 (x+2)
y-1 = 3x+6
y=3x+7

Answer 2

(y-1)/(x+2) = 3

Answer 3

...shudder... point slope format; ewww!!

Answer 4

a(x-x1) +b(y-y1) = 0

Answer 5

<a,b> is normal to the plane :)
