# Math Help - linear functions

1. ## 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.
