    How do you find slope-intercept

    I have to write an equation y=mx+b, I know the slope (m) and a point that the line passes through (3, 2)

    Slope is 1/2

    start with the point-slope form ...

    y - y_1 = m(x - x_1)

    then convert to slope-intercept form

    Slope is 1/2
    y = \frac{x}{2} + b.

    Now substitute (3, 2) and solve for b.
