What is the equation of a line passing through the point (a, b) and having a slope of b?

Question

anonymous · Answer

The point-slope form of a line with a slope of m that passes through the point
$$(x_o,y_o)$$
is:

$$y-y_o = m(x-x_o)$$

anonymous · Answer

I have 
y=-bx-b(1-a)
y=bx-b(a-1)
y=1/bx+b(a-1)
y=-1/bx+b(1-a)

:/ I dont know how to get it in the right form, it doesnt look like any point slope i have ever seen

anonymous · Answer

I cant see how they got any of those 4 options, i have no IDEA which one is correct

anonymous · Answer

If we plug in what we know, we'll get:
$$y - b = b(x - a)$$
$$y -b = bx-ab$$
$$y=bx-ab+b = bx+b(1-a)$$

anonymous · Answer

Which is equivalent to:
$$y=bx-b(a-1)$$
