Question

Write in standard form the equation of a line passing through the point (-3, 4) and having the slope m = 2.

Answer 1

$\begin{gathered} y=2x+b \\ 4=2(-3)+b \\ 4=-6+b \\ 4+6=-6+b+6 \\ b=10 \end{gathered}$

then the equation in standard form:

$\begin{gathered} y=mx+b \\ y=2x+10 \end{gathered}$
