Do it like this one:
-------------------
This is a 2 step process. First find the slope of the line thru the points.
slope, m = diffy/diffx
m = (5-1)/(3-2)
m = 4
---------
Now use y = mx + b with either point to find b, the y-intercept.
y = mx + b
5 = 4*3 + b
b = -7
-------
y = mx + b
y = 4x - 7 is the answer.

(3,-4) (6,1)
Y=mX+b
m=(y2-y1)/(x2-x1)
m=(1+4)/(6-3)
m=5/3 is the slope.
-4=5/3*3+b
-4=5+b
b=-4-5
b=-9 ans. for the Y intercept.
y=5x/3-9
