    linear functions

    Determine the linear function whose graph is a line with a slope of 1/4 that contains the point (2,5). I have Mathway but I don't know how to input this. Help!

    Use the point-slope-formula of a straight line:

    The line l with the slope m passes through the point P(x_P, y_P) if it has the equation:

    \dfrac{y-y_P}{x-x_P} = m

    Plug in the values you know and solve for y.
