You can put this solution on YOUR website! A line passes through the points (-10,-4) and (-1,2) .
What is the y-intercept of the line?
-------
!st:: Find the equation of the line.
slope = (2--4)/(-1--10 = 6/9 = 2/3
----
Form:: y = mx + b
----
Solve for "b"; it is the y-intercept.
2 = (2/3)(-1) + b
2 = -2/3 + b
b = 7/3

2 = -2/3 + b
b = 7/3
==============
b = 8/3, not 7/3
