ok. AB: y=12+1, C(0,3) write an equation for the ;ine parallel to AB that contains point C
OpenStudy (anonymous):
y=12x+3
OpenStudy (anonymous):
see now i wish i was that good, this is my first year in geo.

you have to do with lines. Straight lines. And with points. Points A(x,y). Straight lines are of the form y=ax+b. The plus b stuff shows how upper or lower is the line from another parallel line. the a stuff shows the inclination of the line. For the lines to be parallel you need to have ax the same, and for the up-down stuff you use +b. So in order for the line to cross point C, you need y=12x+b. However for C, x=0 and y=3. so you end up getting 3=12*0+b. so b=3. So the new equation is y=12x+3
