    So we need an equation of the form y = mx + c where m is the slope and c is the y-intercept.

    C is easy, C (the y-intercept) is the point where the line crosses the y axis.

    One at a time, so first we find C. Can you see on the picture where the line crosses through the y axis?

    y=-2 is correct. because you have a straight horizontal line (y), thus no x...If it is vertical then you have x not y
