Question 392706: I am having a hard time finishing this problem.
I need to find the equation of the line containing the given pair of points.
(-7,-3) and (-5,-4)
This is what I get so far.
-4-(-3) 1
------- = - -
-5(-7) 2
y-3=m (x-x)
y-3= 1/2 (x-x)
y-3= 1/2 (x-(-7)
y-3= 1/2 - ?? And this is where I keep getting lost I know I am suppose to multiply 1/2 and -7 but I keep getting the wrong answer somehow each time.... I know I am then suppose to subtract 3 from both sides to get y by itself but I am confused by then..I know the final equation should be I believe y= 1/2x- ??
