Answer:

y2 = m(x2 - x1) + y1

Step-by-step explanation:

Given the slope formula :

m = (y2 - y1) / (x2 - x1)

To obtain an equivalent expression :

We cross multiply :

m(x2 - x1) = y2 - y1

Making y2 the subject ;

Add y1 to both sides

m(x2 - x1) + y1 = y2 - y1 + y1

m(x2 - x1) + y1 = y2

y2 = m(x2 - x1) + y1
