Question 784606
One way to solve that is rearrange y=mx+b into b=y-mx, and then caclulate the slope between the points and substitute one of the points into this formula for b.  In fact, to show this all in one step (and then leave the remaining compuation to you, or here, undone):


Choosing the point (-1,2)...
{{{b=2-((2-(-4))/(-1-(-10)))(-1)}}}
