Write an equation of a line thru (3,-1) and (-1,-7)
2 answers:
Slope form
M=y2-y1/x2-x2
M= -7 -(-1)/-1-3
M= -6/-4
M=3/2 So 3/2 is your slope
Now use one if the pair points
(3,-1) and slope to find b.
-1=2/3(3)+b
-1=2+b
-1-2=b
-3=b Y=2/3x-3
-1 - (-7) over 3 - (-1) = M
-1 + 7 over 3 + 1 = M
6 over 4 = M
6/4 = M
3/2 = M
