**Algebra uno help please. :)**

Write an equation of the line that passes through the point ( 8,3) and has the slope of 1/4 So, I think you would write it as Y=1/4x+B and, you'd plug in 8 for the x, and 1 for the y. So you'd get 1=1/4(4) + B And you'd get.. 1=1+B So, subtract one from each side 0=b y=1/4x+B ...
