To learn about the relationships between parallel and perpendicular slopes, try this lesson on slope.Find a formula for the line parallel to the line y=20-4x and containing hte point (3,12)
Yes; parallel lines have the same slope.so, after the lesson I read, could I solve this by saying that -4 is the slope parallel?
Try using the methods explained and demonstrated in the lesson on straight-line equations (in the link provided earlier).I don't know how to use the point (3 and 12) to think of an equation
I think you did the following:i get y-12 = -4x+12 and then get y= -4x +24????
