Use the point-slope form:



where are the coordinates of the given point and is the slope is obtained from the fact that parallel lines have identical slopes.

Once you have plugged in the values for , , and , solve the equation for in terms of everything else to get the equation into form.

Hi,

Line passing through the Pt(x,y): (-1, -3) that is parallel to the line y = 8

must be y = -3
