Question 405841: Here is another one. Find an equation of the line containing the given pair of points. (1/4,-1/2) and (3/4,1)
The answer to the equation of the line is y= 3x-5/4. I did not get this answer and I don't know how they did. What am I missing?
My answer was y=3x-3/4.
Thank you for your assistance,
Demi

m=(1--1/2)/(3/4-1/4)
m=1 1/2/1/2
m=3
--------------
y=mx+b
1=3(3/4)=b
1=2 1/4+b
b=-5/4
-----------------
y=3x-5/4
