Substitute the point coordinates into the point slope formula: [tex]y-y_1=m(x-x_1)[/tex]. Substitute the slope 1/4 for m, 3 for y_1, and 8 for x_1.
[tex]y-3=1/4(x-8)[/tex], distribute 1/4 inside the parentheses.
[tex]y-3=1/4x-2[/tex], add 3 to both sides.
[tex]y=1/4x+1[/tex]; the slope-intercept form of a line is y = mx + b, where b is the y-intercept, so in this line the y-intercept is A. 1.
