When you are given a point through which a line passes and the slope of that line, you can calculate the equation of that line. The general equation to solve this kind of equations is called as pointslope form. The point slope of a line passing through (a, b) with slope of m is (y  b) = m * (x  a). Now substituting the values in the above equation you can obtain the equation of the line in terms of x and y. In case you are given with two points first find the slope of the line which is the ratio of difference of y coordinates to the difference of the x coordinates and substitute it in the above equation using any one of the points. This video shows how to find the equation of a line in point slope form.
