Question

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

Answer 1

A. y = −bx − b(1 − a)
B. y = bx − b(a − 1)
C. \[y=\frac{ 1 }{ b}x+b(a-1)\]
D. \[y=-\frac{ 1 }{ b }x+b(1-a)\]

Answer 2

(y-y1) = m (x-x1)
(y-b)=b(x-a)
y = b(x-a) + b
y = bx - ba + b
y = bx - b(a - 1)
