Question

Find an equation of the line that satisfies the given conditions.
Through (6, 7);  parallel to the line passing through 
(7, 5) and (3, 1)

anonymous · Answer

First find the slope of the line
since you know it is parallel to the line (7,5) and (3,1) you can simply find the slope for that line which is 
m=(Y2-Y1)/X2-X1)=4/4=1

now use point slope formula
Y-Y1=m(X-X1)
Y-7=X-6

slope of the given parallel = 1 ====> y=mx+b ===> y=x+b ==> 7=6+b ==> b=1 ==> the required equation is y = x+1

ooh okay...i just didnt know the first step..i think i can figure it out from there, thank you! if you have time i had a previous question about average velocity that i am stumped on haha...thanks guys
