Given

How to figure out an equation in slope-intercept form given the slope and a point

Solution

Let the point be (a,b) and slope m

$\begin{gathered} y-b=m(x-a) \\ \text{open the bracket} \\ y-b=mx-ma \\ we\text{ can make y the subject of the formula} \\ y=mx-ma+b \end{gathered}$

you can write the equation of any line in the form of y = mx + b
