Question

Aline has a slope of 2, and passes through the point (6,8). Determine which equation in slope intercept form) represents this line.

Answer 1

the equation is of the form y = mx + b, where m = 2, then

for b:

$\begin{gathered} y=mx+b \\ 8=2(6)+b \\ 8=12+b \\ 8-12=12+b-12 \\ b=-4 \end{gathered}$

equation is

$y=2x-4$

answer: C.
