(6,4) and (-3,1)
m = (1 - 4)/(-3 - 6)
m = (-3)/(-3 + (-6))
m = (-3)/(-9)
m = (1/3)
(6,4), m = (1/3)
4 = (1/3)(6) + b
4 = 2 + b
b = 2
ANS : y = (1/3)x + 2

The slope of the line is 4-1/6--3=3/9=1/3
so as before
y=x/3+b
so 4=6/3+b
and hence b=2
so line has equation y=x/3+2

You have to use the formula : y = mx+c
Substitute the given numbers in the formula
4 = 6m+c ------------------ (1)
1 = -3m +c ------------------- (2)
(1) - (2) gives you 9m = 3 ------------ m = 1/3
Substituting this in (1) ------------- c = 2
Now the equation for the line would be
Y = (1/3)x + 2 or 3y = x + 6

y=mx+b
m=(y2-y1)/(x2-x1)
solve for m, plug in one of the points, solve for b (y-mx=b), then you'll have your equation.
For example:
points are (3,5) and (-2,4)
m= (5-4)/(3- -2) = 1/5
5-(1/5)*3=b b=2/5
so the equation would be y=1/5x+2/5
hope that helps!

Find its slope. Then write y = m x + b. plug in 6 for x and 4 for y and the slope for m, and solve for b
