Question 23002: can you please help me on origin. How do you write an equation for the line containing the origin and the points (2,1)
Please help me im clueless
I know that origin has something to do with slop and the slope formula is Y2-Y1 over X2- X1. I have no idea what to do and i have a teacher that does not clearly explain things and this is my last resort.

If the line contains the origin, that means that in the equation of a line
y=mx+b

the value of b = 0. All you need is the slope, which is rise over run, up 1 and over 2 to get from (0,0) to (2,1). The slope m is rise over run = 1/2, so the equation is
