Thank you for the opportunity to help you with your question!

First we find the slope:

m = y2 - y1 / x2 - x1

= 12 - 8 / 4 - 2

= 4/2 = 2

So, y = 2x + b

Since the line passes through the origin, b = 0

Therefore the equation of the line is

y = 2x


Please let me know if you need any clarification. I'm always happy to answer your questions.
