The difference between the points will give you the slope:

= = slope
Then use the formula y=mx+b to find the y intercept (the "b" in the formula)
Pick a point and plug in the values for x, for y and for m (the slope), I will use the point (3,7)
Y=(m)*X+b
7=(4/3)*3+b
7=4+b
3=b
So now we put the values into our equation:
y=mx+b
